Bug 316711

Application: muon-updater (1.9.80)
KDE Platform Version: 4.10.1
Qt Version: 4.8.3
Operating System: Linux 3.5.0-26-lowlatency x86_64
Distribution: KXStudio 12.04.1

-- Information about the crash:
- What I was doing when the application crashed:
I was updating my system with muon when it crashed.  I noticed the updates were done when I restarted. Perhaps also related is the fact that the packages to update were not shown as 'selected' while they were. Also, there was no way to select or deselect them by clicking on the square box. The select-box stayed empty. I don't know if it is a part of the problem, but since it's the first time I experience this, and see a Muon crash, I hope it is.

-- Backtrace:
Application: Muon beheerder voor bijwerken (muon-updater), signal: Segmentation fault
