Bug 301791

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.3.7-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
Resumed laptop from suspend to ram, attached second monitor, activated second monitor in system settings.

Since I rebuilt my system using gcc-4.7.0 this crash occurs every time. The Plasma Desktop then restarts and I can use the external monitor along the panel fine, but Dr.Konqi keeps popping up first.

- Custom settings of the application:

Rebuilt my system using gcc-4.7.0

(A side note: DrKonqi is currently unable to search the bug reports. I have searched via web interface but could not identify a possible duplicate.)

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (kdeinit4), signal: Aborted
