Bug 320230

Application: muon-installer (2.0.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-22-generic x86_64
Distribution: Ubuntu 13.04

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

All I did was hover over an icon from within the category selection. It crashed at that point.

The crash can be reproduced every time.

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