Application: plasmashell (5.18.5)

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 5.6.14-1-default x86_64
Windowing system: X11
Distribution: openSUSE Tumbleweed

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

I enabled the system tray service "Weather Report".  Then openned its settings.

There are 4 tabs.
  -Weather Station
  -Appearance
  -Units
  -Keyboard Shortcuts

The second time I enter the "Units" tab, within the same Settings dialog session, Plasma crashes.

If I enter "Units" tab and save settings, then re-open settings window and go to Units tab, it is ok.

Identical crash if I go through a desktop widget for Weather Report.

The crash can be reproduced every time.
