Bug 327176

Application: muon-updater (2.1.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
Attempting to update my packages.
Happens every time I search for updates, no updates are subsequently installed via muon(28 were reported available today). All 28 updates successfully install via terminal however muon stil crashes on clicking the gear icon after successful terminal based update. The Muon window appears briefly and the "apply updates" button un-greys at the moment before the crash occurs however no updates are displayed in the update list. Another bug report prompt is displayed.

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