Bug 294844

Application: muon-installer (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
The program crashes every time I start it. I'm not experienced enough to compare backtraces of other reports about crashing on startup so I'm not sure if I've just duplicated a possible bug.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon Software Centre (muon-installer), signal: Segmentation fault
