Bug 293896

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 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I simply clicked on the desktop icon.
- Unusual behavior I noticed:
The bouncing mouse cursor appears, then the object dialog box pops up, but never fully populates. Then, it disappears and the crash report appears. 
Computer Info: Kubuntu 11.1
Linux 3.9.9-15-generic
KDE SC Version: 4.7.4
P4M900-M4
4GB RAM
590GB HD (WL640GSA3272)
Intel Duo Core 2.13GHz
NVIDIA 8400 GS/PCI/SSE2 (290.10)

The crash can be reproduced every time.

-- Backtrace:
