Application: plasma-netbook (0.1)
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-23-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
- Unusual behavior I noticed:
Every time i open kontact and try to switch to another application using the
netbook bar a contentless window appears and starts flashing until an activity is selected.
However the kontact window cannot be closed through "x" button because the contentless windows
gets focused.

If I close the window plasma crashes

KDE SC 4.5 RC1 from kubuntu-ppa/beta repos

The crash can be reproduced every time.

-- Backtrace:
