software-store crashed with KeyError in <module>()

Thanks for your bugreport.

This sounds like your python stack was not in a consistent state. Did this happen during a upgrade? Is it reproducable? What does it print if you run it from the commandline?

I can confirm and reproduce the error.
No updates or anything else. Everytime I start software-store it crashes (apport shows up)
*but* software-store doesn't crash really, I can continue using it without problems.

sebner@ubuntu:~$ software-store
0:00:00.022931240 16523 0x8ac32d0 ERROR pyplugin gstpythonplugin.c:267:pygst_require: the pygst module is not available!
Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/pygst.py", line 28, in <module>
    import sys
KeyError: 'pygst'

@Stefan:
Thanks for confirming. What does happen if you run (in a terminal) the following commands:

$ python -c 'import sys'

$ python -c 'import gtk'

$ python -c 'import gst'

It should display nothing for all them but I wonder if that is the case for you as well?

Yep, you are right.
No output for any of these commands.

@Michael:
Interestingly I couldn't reproduce the error yesterday but today after a normal ubuntu start
the bug is still present. Dunno why it fails with pygst. I'm sure the --debug log doesn't show you anything new but I attached it nevertheless:
