Bug 314925

Application: muon-updater (1.9.80)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I started muon manually, clicked 'Check for Updates'. My wild guess: maybe the automatic update was running/started simultaneously.

After the crash I got the System Notification that 'Software updates are available'

- Custom settings of the application:
I'm running kde 4.10 from kubuntu beta backports on kubuntu 12.10

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