Bug 284970

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 x86_64
Distribution: Ubuntu 11.10

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

I was trying to unlock the package "phonon-backend-xine". I opened the menu on the package and chose the option "unlock". This action closes the muon and showed the window bug. when I restarted the muon, the unlock action was not completed. I could not reproduce the error again. The second attempt, the muon not closed unexpectedly and also does not unlock the package.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Gerenciador de pacotes Muon (muon), signal: Segmentation fault
