Application: systemsettings5 (5.17.5)

Qt Version: 5.12.5
Frameworks Version: 5.70.0
Operating System: Linux 5.6.0-2-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid

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

1. Open System Settings
2. Click "Workspace Behavior"
3. Click "Screen Locking"
4. Wait 1-2 seconds

(This is a fresh Debian Testing KDE install -- installed today! -- that I have customized very little.)

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
