Bug 363679

Anytime the muon update manager is started, the application window opens but crashes before completely starting.  The initial run crashes after the busy icon spins for a while indicating (I assume) that it was updating the package indexes.  Subsequent runs crash immediately after the window appears presumably because the index is already up to date. 

Reproducible: Always

Steps to Reproduce:
1. run muon-updater, from the command line or from a launcher
2.
3.

Actual Results:  
Segmentation fault (core dumped)
