Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.38-ck x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I have two pannels. On one there is a fully set up system tray, with the notifications option disabled, for some reasons unrelated to this bug.
I have a second panel, where I then added a second system tray. When I then open up the settings dialog of that second systray and deselect everything except the notifications option, and press apply, plasma-desktop will crash.

The crash can be reproduced every time.

-- Backtrace:
