KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.1-6.slh.1-aptosid-amd64 x86_64
Distribution (Platform): Debian unstable

-- Information about the crash:
- What I was doing when the application crashed:
changing plasma-desktop to plasma-notebook makes the crash

The crash can be reproduced every time.

-- Backtrace:
Application: Interface « Plasma Netbook Shell » (plasma-netbook), signal: Segmentation fault
