Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-18-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
After the crash and restauration there is always an (empty) notification of the OpenActivities Plasmoid. The crash started after I moved it into the panel. When it was on the desktop, there was no crash.
Now after the crash, when I click on the OpenActivities Pasmoid, it contains part of my Desktop (the folderview plasmoid). Not only the graphic, but the active content. I can click the folders and the files.

The crash can be reproduced some of the time.
