Application: muon-updater (2.1.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64

-- Information about the crash:
I had a notification for new packages available, clicked on it, muon started lading the package information - and then it crashed.

The crash can be reproduced every time.

-- Backtrace:
