Bug 294024

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

-- Information about the crash:
- What I was doing when the application crashed: Attempting to load additional applications thru the Muon software loader system, It starts then immediately crashes into the bug reporting system		

- Unusual behavior I noticed:  During first upgrade of system files the Muon system got stuck at 49 percent on identity or login updating info.  I force shutdown and restarted pc, and now the Muon System will not start up.  I have tried going into Kate and going in as su or root to update it manually with aptitude but it gives me authentication error.

- Custom settings of the application: first instatallation.

The crash can be reproduced every time.

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