Bug 295741

Application: muon-installer (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Burning an ISO and copying files to a USB stick.

- Unusual behavior I noticed:
Muon started, then shut down.  This has happened since a clean install of Kubuntu 11.10	

- Custom settings of the application:
None at all - fresh out of the box.

The crash can be reproduced every time.

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