--- Comment #17 from Carsten Pfeiffer <pfeiffer@kde.org> ---
I'm having a similar crash even with plasma-framework 5.12. This occurs when I
do the following:
- used notebook standalone (just the notebook display)
- suspend
- put notebook into docking station, which has two external displays attached
- resume from suspend

kscreen will then disable the notebook display and enable the two external
displays. When I then invoke krunner, it crashes.
