Application: plasmashell (5.18.0)

Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 4.15.0-76-generic x86_64
Windowing system: Wayland
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
I updated to 5.18 on an older laptop.   Both regular and Wayland sessions crash. I'm also running 5.18 on a M$ Surface Pro 2, and that one runs without issues. 

Thanks!!

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
