Bug 326148

Application: muon-updater (2.0.65)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

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

Dist-upgrade from Raring to Saucy (13.04 -> 13.10)
Muon reports new software updates, after click it crashes. Console APT is working.

The crash can be reproduced every time.

-- Backtrace:
Application: Správce aktualizací Muon (muon-updater), signal: Segmentation fault
