Janitor crash when scan finish ends on apt cache

[Angel Guzman Maeso]

0.7.3 on Quantal.

This is the traceback:

[utils.icon][WARNING] get_from_list for application-x-generic failed, try next (icon.py:56)
Exception in thread Thread-1:

The line "[utils.icon][WARNING] get_from_list for application-x-generic failed, try next (icon.py:56)" is showed 4000 times, one per package to clean. And it is very slow (3-4 min) to find all packages.

4000 times?

So that's about 4000 packages to clean, right? Have you already cleaned all the packages?

[Angel Guzman Maeso (shakaran)]

Exactly 4344 (one line per package). I have a lot packages to clean (quantal upgrade and precise), I never cleaned the packages.

Updating to 0.7.3-0~bzr1866+20120624~quantal1 still doesn't solve the problem.
