Application: plasmoidviewer (1.0)
KDE Platform Version: 4.10.60 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.7.6-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was using the plasmoidviewer, but the same happens with plasma-desktop. I don't think it's very hard to reproduce.

Open -> settings -> boom

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Widget Viewer (plasmoidviewer), signal: Segmentation fault
