Sentry Crash Report:

Description john doe 2020-05-24 19:11:04 UTC 
Application: systemsettings5 (5.18.5)

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 5.6.12-1-default x86_64
Windowing system: X11
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:
clicked on Yast in System Settings

The duplicates suggested to me when submitting all linked to original reports stating it's fixed, however it happens here with 100% rate. Launching Yast manually works perfectly fine.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

This was actually a regression in kcmutils 5.70.0 and will be fixed in KDE Frameworks 5.71.0, see bug#421566.
