New issue 489 by karel.fajkus: Error 409 Conflict when tagging some photos
http://code.google.com/p/googlecl/issues/detail?id=489

What steps will reproduce the problem?
1. googlecl picasa tag --user m...@user.name --query "P1110123" --tag test

What is the expected output? What do you see instead?

It should tag the photo, but "409 Conflict" error is given instead:

Traceback (most recent call last):

   File "google", line 835, in main

gdata.photos.service.GooglePhotosException: (409, 'Conflict', "<?xml

[Snip.] The XML continues and contains all the details of the photo in  
question.

It's happening to about 10% of files uploaded to PicasaWeb in the last 2  
weeks. I didn't try older files and all was OK about 3 months ago, on the  
same Google account.
When a photo exhibits this error, it does so even when googlecl is run from  
another computer, another location/network (same photo and same user  
account of course).

What version of the product are you using? On what operating system? What  
version of gdata-python-client (aka python-gdata)?

googlecl 0.9.13 on Windows
python-gdata supplied with googlecl

TIA.
