Sentry Crash Report:

Description Dennis Schridde 2019-11-01 01:04:48 UTC 
Application: systemsettings5 (5.17.2)

Qt Version: 5.12.5
Frameworks Version: 5.63.0
Operating System: Linux 5.3.7-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

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

I switched the Global Theme from Breeze Dark to Breeze Dark (i.e. Breeze Dark should have been selected before, but I could not really see it being selected in the Global Theme dialogue, so I selected it again). Pressing "Apply" crashed System Settings.

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