Bug 291467

Application: muon-installer (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

- Unusual behavior I noticed:

i just wanted to start, but the application crashed after opening the window in kde.
the "sudo apt-get  remove muon-installer"  and  later "sudo apt-get install muon-installer" did not solve the problem

The crash can be reproduced some of the time.

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