-- Information about the crash:
This is likely related to bug #509282 - I have an interesting kscreen
configuration and when trying to debug stuff around it, Plasma started crashing
repeatedly when disconnected external screens. I tried to workaround both
issues by removing the plasma configuration file in ~/.config , but not the
kscreen configuration files in ~/.local/share/kscreen - and then I got this
crash on login

The crash can be reproduced every time.
