Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.90 (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.6.6-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

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

Starting up the newly-compiled system.  (Since I have a hotkey for konsole, I could launch that and try again, got the same problem)

- Custom settings of the application:

I have a plasma app on the desktop (the stock ticker).

The crash can be reproduced every time.

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