Bug 422332

Application: plasmashell (5.18.90)

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 5.6.14-1-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed: I just logged into Plasma Wayland through sddm. Nothing looked wrong, but the crash icon shows up in the bar, so I might as well report it. I have my monitor conected to my laptop, and the laptop screen's disabled. It seems to happen every time I log in like this.

The crash can be reproduced every time.

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