-- Information about the crash:
I think it occurred to me already twice: Setting my laptop into standby,
changing the monitor configuration (i.e., disconnecting some and connecting
another external monitor), and resuming from standby seemed to trigger a crash
of kded6. This time, the disconnecting part involved undocking from a docking
station. I do not remember the details for the previous occurrence.
In case that’s relevant: AFAIR the laptop was a significant time in standby
when this happened (> 30min).
The reporter is unsure if this crash is reproducible.
