Errors preventing Mnemosyne from starting.

[KC]

Hi guys, I am using Mnemosyne on Linux Mint 18.02. Yesterday I tried to create new card groups under (de)activate card and errors showed up after a few groups were created. Now when I start the program the following error messages pop up:

An unexpected error has occurred.
Please forward the following info to the developers:

Please help!

Hi,

I suggest you first check if you can open the svg file that Mnemosyne complains about in another program.

Also, as a workaround, if you don’t choose ‘Q and A in two windows with adaptive size, this error should go away.

But do let me know if the svg is OK, and you still get an error.

Cheers,

Peter

Thanks for the help! It looks like that svg was broken. Now everything is fixed!
Cheers,
Karl
