Bug 326301

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've seen lot of other similar reports but none mentionned that the crash occurs only when mouse pass over the window.
Meaning, there is no crash until the mouse goes over the main window.
Hope this help

The crash can be reproduced every time.

-- Backtrace:
Application: Logithèque de Muon (muon-installer), signal: Segmentation fault
