Bug 329528

Application: muon-updater (2.1.1)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

I started Muon updater and used Ctrl+R to check for new updates. While loading the update list, Muon updater crashed. No other programs were running at the time.

The crash can be reproduced sometimes.

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