Application: muon-updater (1.3.1 "Daring Dalek")
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Crashed just before it would have given me the list of updates.  Muon usually gives me an icon in the system tray stating I have new updates a few seconds before Muon finishes searching for updates. This did not happen this time. Also I still have Apper still installed which may be causing an issue since it still searches for updates on its own.

-- Backtrace:
Application: Muon Update Manager (muon-updater), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
