Bug 292487

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 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Fresh install of Kubuntu 11.10 x64 on Acer extensa 4420 
I started Muon Software Center and it never loads anything useful, it just goes straight to a segmentation fault.

Muon Update Manager also had an issue, when doing a software upgrade it stopped responding at 56% I had to use dpkg --configure -a to repair the upgrade. 

- Custom settings of the application:
no customizations, just fresh install.

The crash can be reproduced every time.

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