Application: plasmashell (5.17.0)

Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 4.15.0-65-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:

Dolphin, Konsole and a pdf reader was open. This didn't happend in previous versions, but started after I updated to 5.17. The desktop turns Black and panel doesn't show up, most of the times I have to reboot from the konsole.

The crash does not seem to be reproducible.

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