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:

I usually don't use the updater feature in Muon, I prefer to either use aptitude dist-upgrade or the regular Muon Package Manager to update my system. When I click on the Updater in my taskbar, it will show me the updates. When I click on Update and enter my password, the Updater crashes.

The crash can be reproduced every time.

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