Sentry Crash Report:

Description mateusz.walas@protonmail.com 2020-10-18 10:42:59 UTC 
Application: systemsettings5 (5.20.0)

Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.8.14-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

I was just installing new Global Themes. I think it's say to say most of the time I get a crash (after providing root password for the popup that updates SDDM). Nothing else to say here, really, just scrolling down the list of themes and installing the ones I like.

The crash can be reproduced sometimes.

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