Application: plasmashell (5.16.80)

Qt Version: 5.12.3
Frameworks Version: 5.63.0
Operating System: Linux 5.2.5-050205-generic x86_64
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
I suspended my laptop, I waked up it a few minutes later and drkonqi was present in systray indicating Plasma crash. This crash happened on Wayland.

The crash does not seem to be reproducible.

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