Bug 326502

Application: muon-installer (2.0.65)
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: I just open it up, the window was not frozen, all the buttons are okay to use but about a second ater opening it, it will just close opening this crash report.

The crash can be reproduced every time.

-- Backtrace:
Application: Muon Software Center (muon-installer), signal: Segmentation fault
