Bug 329755

Application: muon-updater (2.1.2)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
Everytime I click on the updates' tray icon, the Muon Updates window shows up for a few seconds, then it crashes (showing the bug report assistant).

The crash can be reproduced every time.

-- Backtrace:
Application: Gestore Aggiornamenti Muon (muon-updater), signal: Segmentation fault
