Bug 269558

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.41 (4.7 >= 20110106) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
1. Right-click on the desktop, select "Desktop Settings"
2. Press Enter as soon as the window comes up (but so that it and the list of wallpapers aren't painted/loaded yet)
3. Crash!

Note: Pressing Esc doesn't cause a crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma-työpöytäympäristö (kdeinit4), signal: Segmentation fault
