Qt Version: 4.6.0
Operating System: Linux 2.6.32-7-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
The opendesktop widget crashes without starting when clicked to add the widget to the desktop.

Currently one one activity area is used with a home folder view widget and luna widget.

Bug 218421 is related to this bug posted by me. But that bug report didnt contain any backtraces.

The crash can be reproduced everytime.
