Description Sylvia 2020-01-04 06:59:45 UTC

Application: systemsettings5 (5.17.4)

Qt Version: 5.12.5
Frameworks Version: 5.64.0
Operating System: Linux 5.3.16-300.fc31.x86_64 x86_64
Distribution: Fedora 31 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
I was configuring different parts of my desktop such as Plasma style and Colours. If I switch between tabs or configure things too quickly the app will crash. Same if I'm trying looks and apply more than once different styles, the app will crash.
No other strange behaviour is noticed. 
Not using Aurorae engine.

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