Comment 7 for bug 811915

Based on the number of dupes, I guess I need to raise the priority. It isn't happening for everyone, but not sure what the specific history is for the users hitting it. It is only for upgrades, and not all upgrades.

The problem seems to be related to switching from pycentral to dh_python2, it isn't cleaning up the old .pyc files. The Work around is to remove /usr/lib/python2.*/dist-packages/gwibber

It looks like i need to clean those files in the package, but I would think pycentral should do that automatically, so want to ask around first.
