Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090706))
Qt Version: 4.5.2
Operating System: Linux 2.6.27.23-0.1-pae i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
KDE and plasmoid are built from svn trunk. 
Reproducing steps: add a nm widget to panel. After this plasma crashes.
