Unable to delete picasa photos from albums

[antoni...@gmail.com]

Hallo, I am running 0.9.13 version of googlecl on ubuntu 11.10
 I have installed it a week ago and i use it for uploading and delete pictures from picasa at specific albums. The google picasa post album_name /home/sourcedir --tags command works perfect and i can upload hundred of pictures. The problem is in google picasa delete album_name -q tags --yes or google picasa delete album_name -q tags. The output is the same if i try to delete one or more pictures:

Traceback (most recent call last):

    return self.retry_operation(*args, **kwargs)
  File "/usr/lib/pymodules/python2.7/googlecl/base.py", line 387, in retry_operation
    raise unexpected
Sometimes the delete command works in very few photos but not always. Never works for deleting many photos.
Can you help me please?
