Application: muon-installer (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64

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

Removing applications, then while I was just navigating through the installed
softwares it used to bring me back to the main page several times. After
insisting on that, it crashed.

The crash can be reproduced every time.
