The new plasma system monitor crashes every time when I close it. Also happened with plasma 5.21. 

Btw, the crash handler does not support to report system monitor crashes directly, I get "This application is not supporetd in the KDE bug tracking system"

Application: plasma-systemmonitor (5.22.0)

Qt Version: 5.15.3
Frameworks Version: 5.82.0
Operating System: Linux 5.8.0-55-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.0
Distribution: KDE neon User Edition 5.22

-- Information about the crash:
<In detail, tell us what you were doing  when the application crashed.>

The crash can be reproduced every time.

-- Backtrace:
Application: System Monitor (plasma-systemmonitor), signal: Segmentation fault
