Sentry Crash Report:

Description Peter Ped Helcmanovsky 2020-04-14 22:18:42 UTC 
Application: plasmashell (5.18.4)

Qt Version: 5.14.1
Frameworks Version: 5.69.0
Operating System: Linux 5.5.17-050517-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
I was launching (from bash script in "for" loop) and exiting one app (by hitting Esc in the app) (the app is using mono, but I believe it's not related to the crash as I have seen similar already few times) in rapid succession and after one of the exits the task bar disappeard for split of the second, then reappeared with the crash report.

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