Application: systemsettings5 (5.21.1)

Qt Version: 5.15.2
Frameworks Version: 5.79.0
Operating System: Linux 5.4.0-66-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.1
Distribution: KDE neon User Edition 5.21

-- Information about the crash:
#433025 sounds like the same bug, but claims to have been fixed in 5.21.1; I'm running that version and still seeing this crash.

- What I was doing when the application crashed:

To reproduce:

1) Open System Settings
2) Switch to Firewall
3) Switch to something else (eg Audio)
4) Switch back to Firewall
5) System Settings crashes

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
