Description kde 2013-10-10 06:53:57 UTC 
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 i686
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Clicking OK in the notifier window when it said there were new updates available.
Updater opened and displayed "No updates available".
After a while the notifier popped up again. Updater segfaulted after clicking OK.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Muon-Aktualisierungsverwaltung (muon-updater), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
