-- Information about the crash:
- What I was doing when the application crashed:
use Wayland, connect an external monitor and set multi-monitor mode to 'Switch to laptop screen'.
Logout, start Plasma Wayland again, drkonqi icon in system tray indicates Plasma crash.

The reporter is unsure if this crash is reproducible.
