--- Comment #2 from Pascal Niklaus <pascal+...@niklaus.org> ---
Ok, now it happened again, but I doubt that I see the crashes that caused the
problem. In the morning, all was fine despite these dumps. Upon booting in the
afternoon, all activities and desktop settings disappeared again. I wonder
whether this is related to restoring open applications.
