-- Information about the crash:
Most probably this is related to one of the bugs I marked as possible duplicates...

- What I was doing when the application crashed:
 Just logged out.
- Custom settings of the application:
 I use the weather plasmoid.... I just found the related crashes with this plasmoid.
Haven't tried without it thought yet.

The crash can be reproduced every time.
