Application: systemsettings5 (5.17.90)

Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 4.12.14-lp151.28.36-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.1"

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

1. Open systemsettings5
2. Click Regional Settings
3. Click Formats

It always crashes. Note that I see KMail also crashing in the same place when I start it in QT.

The crash can be reproduced every time.

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