Bug 426630

Application: plasmashell (5.19.5)

Qt Version: 5.15.1
Frameworks Version: 5.73.0
Operating System: Linux 5.7.11-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Fresh login into Plasma (Wayland) session on OpenSUSE Tumbleweed (20200915-0). External monitor connected by USB-C/DisplayPort and laptop monitor disabled. The crash happens every time I login, i.e. there is a notification from DrKonqi in the tray, but the desktop actually runs normally. If not for DrKonqi notification, I wouldn't know the crash happened.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
