Hi,
I've suddenly run into a number of errors and problems with Mnemosyne (2.4.1, installed on Windows 10). I'd be happy to make proper bug reports over on Launchpad if they'd be useful but it feels like something deeper has gone wrong and it's time to restore a backup and try again.
Quick summary: Made some images and tab-delimited list for some map cards, tried to import them incorrectly, eventually figured it out but some cards disappeared during card-type conversion; now have reproducible errors in the (de)activate cards window, when converting the type of certain cards, when setting the field mapping for certain card type conversions, and if I try to create a Map card with the Location set to 'Alabama' or 'Alaska'.
Okay, in somewhat more detail, and with the apology that I didn't realise it was going to get so complicated and didn't document much of it:
Wanting to make a bunch of map cards, and finding Timothy Bourke's svgtoquiz unsuitable for my needs, I created some map cards in the program and exported them in various formats as a starting point for importing some of my own (with various attempts including manually editing the cards.xml file inside a .cards file). Importing these didn't work, unsurprisingly - with the exception that a .cards import might have technically succeeded once without seeming to add any cards (!). The manual text file (with two columns, not three) got imported fine too, but when I tried to convert the "front-to-back only" card type to a Map, I got an error in the field-mapping dialog.
In this case the dialog has two combo boxes (front and back) and three options in each (location, blank map, marked map). As soon as I picked something for both combo boxes (I don't recall if it had to be something specific) I got the following error:
---------------------------
An unexpected error has occurred.
Please forward the following info to the developers:
Traceback (innermost last):
File "mnemosyne\pyqt_ui\convert_card_type_keys_dlg.py", line 74, in combobox_updated
TypeError: critical(QWidget, str, str, buttons: Union[QMessageBox.StandardButtons, QMessageBox.StandardButton] = QMessageBox.Ok, defaultButton: QMessageBox.StandardButton = QMessageBox.NoButton): argument 4 has unexpected type 'str'
---------------------------
The dialog otherwise worked and I could repeat the process continually, but the OK button was never enabled so I couldn't progress/do any harm.
I eventually found information on this forum explaining how to import map cards as three columns in a tab-delimited file and tried that, successfully importing them as vocabulary cards. When I tried to convert them, however, I selected all the cards at once (50 pairs of 2 sister cards in this case, a test run with US states) and set the mapping appropriately, and got the following error:
---------------------------

TypeError: 'NoneType' object is not subscriptable
---------------------------
I escaped out of the card browser and went back in and tried with smaller batches, and the error appeared maybe once or twice more but mostly it worked. At the end I noticed I was two states short - Alabama and Alaska, the first two alphabetically, but no different in format to the rest. On one hand, having otherwise valid cards get irreversibly and almost-silently deleted is a pretty big bug, but I already contaminated things since I'm pretty sure I used Alabama and Alaska in the manual attempts at the very beginning.
Figuring it was easier to add them manually, I used the add-card dialog and got/get the following error if the Location field matched one of their names:

---------------------------
However, if I change the Location field (e.g. "Blabama") and then edit it back to "Alabama" in the card browser, there's no error. Compacting the database doesn't appear to have any effect.
Finally - and I'm pretty sure but not certain this was happening before today - while I was doing this I had my cards filtered in the (de)activate cards dialog to make the card browser less cluttered. I've found that the option to filter cards "not having any of these tags" is inaccessible - attempting to use it and checking one or more tags creates the following error when I click OK:

I guess the actual bug is somewhere in the import process, due to it not expecting a crazy person to mess around with the internals of a .cards file, and all the NoneType errors stem from that. I can't see a way to attach files from this interface but I still have what I think is the offending .cards file in question if you want to bother making it literally more foolproof.
I've also noticed some other things that don't seem to have been mentioned recently, and were happening before I started all this map-card importing. Are any of these unknown potentially-worthwhile bugs?
* Sometimes some of the numbered buttons will appear to be active before I show the answer (i.e. they're not disabled). I haven't tried to click one to see if something happens or if it's just cosmetic. The last time it happened it was buttons 2 and 4 only. Not consistently reproducible.
* Dialogs will sometimes appear on my second monitor instead of the same monitor as the main window. Not consistently reproducible.
* The font dialog doesn't remember its settings, and goes back to the default font, size, etc. every time I open it (in this case, MS Shell Dlg 2, Normal, size 8). The font itself is saved as long as I don't open the dialog and click OK (in which case it obviously 'resets').
* Possibly a Windows or Python-on-Windows thing - if I open the 'Add cards' window and then minimise it, clicking on the main window doesn't bring it back to the front and all the controls are inaccessible, making the program appear to be frozen. While that one's fairly obvious, the same thing happens if the Add cards window is elsewhere behind another program's window - controls on the main window are unreachable (as expected for a program with a modal dialog open) but neither of them appears to get focus or come to the front when the main window is clicked.
* Minor, but emojis display differently in the preview window compared to the main screen. I suppose it's just using a different font or font settings? (I noticed when putting some in for phases of the moon; they displayed only as squares in the past so it's a lot less of an issue now anyway.)

Hi,
I'm afraid that if you manually edit cards files without being careful, all bets are off, and you will indeed run into all sorts of weird problems. Unfortunately, I will not be able to give support for that case, so I do indeed suggest restoring from a backup.
If in that case you still get errors, by all means, do get back in touch!
The minor issues you mention at the end of the mail seem all related to the Qt toolkit we use, and not directly under our control. I'll have a look if I can work around them, but in all likelihood they are toolkit bugs.
Cheers,
Peter

Restoring from a backup unsurprisingly resolved all the issues - except for the (De)activate card dialog, which still has the " AttributeError: 'list' object has no attribute 'values' " error if I click OK with the "not having any of these tags" option selected and zero or more tags checked. I can work around that one, but it doesn't seem connected to my tinkering - it persisted across my backup restoration, an uninstall/reinstall, and into a new test database with a few items added from the Add Card dialog.
By the way, I should have said - your program is fantastic! Thanks for making and maintaining it.

Hi,
I've confirmed that issue. Will be fixed in the next release.
Thanks for the report and the kind words!
