Application: muon (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I enabled proposed repository in software sources, then I clicked on full upgrade. After doing these steps I clicked on "unmark all" and muon crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon Package Manager (muon), signal: Segmentation fault
