Bug 321626

Application: muon-updater (2.0.1)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-25-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
I started Muon Update Manager by clicking on the gear-wheel in the system tray, clicked on "update", waited, saw a system notification that security updates are available, and then the Muon window disappeared and the crash reporting assistant appeared.

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