Bug 289838

Application: muon (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 x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
Muon crashes whenever I try to start it. Haven't been able to start it even one time until now.
Removing and re-installing it completely didn't help either

The crash can be reproduced every time.

-- Backtrace:
Application: Muon-Paketverwaltung (muon), signal: Aborted
