We need to see what error you get or a link to the crash report that got created. – Rinzwind Apr 10 '13 at 17:36
What website would you go to enter a crash report? (not everybody knows this) – mdpc Apr 10 '13 at 17:39

This is what I did:

Delete all the *pyc in:


and then:

sudo apt-get install --reinstall python3-gi

There are many reasons this could happen. I spent several hours searching forums for an answer. The thing that worked for me is this:

Change the download source in System Settings -> Software & Updates -> Ubuntu Software.

Fixed it for me.
