Description Bob S. Galbert 2019-12-21 19:30:28 UTC

Application: systemsettings5 (5.17.4)
 (Compiled from sources)
Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.4.5-arch1-1 x86_64
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:
So i went to Systems Settings > Applications Styles > GNOME/GTK application styles and then i switched over to window decorations

- Unusual behavior I noticed:
It was taking a while to switch from GTK application styles to window decorations

- Custom settings of the application:

Nothing?

The crash can be reproduced sometimes.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
