Description Panagiotis Papadopoulos 2009-12-29 17:58:34 UTC 
Application: plasma-netbook (0.1)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.32-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
plasma-netbook crashes when clicking on the "X Running apps" button twice.
The first time I click on it I get the windows list. I then click on any other place in the plasma-netbook shell, so that this list disappears. If I now again click on the "X Running Apps" button plasma-netbook will crash with the attached backtrace

The crash can be reproduced everytime.

 -- Backtrace:
Application: Plasma Netbook (plasma-netbook), signal: Segmentation fault
