-- Information about the crash:
I have a dual-monitor setup. When only one monitor is active I did not
experience any crash.
Both monitors have a full panel on the bottom. Removing the "Icons and
Text-Task Manger" applets from both panels does not resolve it.
I have now removed the widget "Pager" from both panels and now it seems to be
stable. I use a single Desktop and 7 activities.

The crash can be reproduced every time.
