Application: muon-updater (1.2.95 "Daring Dalek")
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.8.0
Operating System: Linux 3.2.0-17-generic x86_64
Distribution: Ubuntu precise (development branch)

-- Information about the crash:
- Unusual behavior I noticed:
first updates gave a panel that colored full darkgray, then I ran Muon updater and it stucked on loading system updates and updates for Wine (upgrade for 64 bits version) 
I reloaded and I got a crash (not fatal)

The crash can be reproduced every time.

-- Backtrace:
Application: Muon beheerder voor bijwerken (muon-updater), signal: Segmentation fault
