Bug 441449

Application: systemsettings5 (5.22.4)

Qt Version: 5.15.2
Frameworks Version: 5.85.0
Operating System: Linux 5.13.12-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: openSUSE Tumbleweed

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

Before the KDE System Settings application crashed the first time, I was trying out some application styles in "Appearance" -> "Application Styles". Now the KDE System Settings application crashes every time when trying to select certain elements, e.g. "Appearance". I really would like to get rid of this condition, e.g. by removing some broken configuration file or whatever...

By the way, when scrolling down to the end of the crash report, several possible duplicates of this bug are suggested. In contrast, the search that was done earlier in the user interface did not return any possible duplicates. Sorry if this is a duplicate after all...

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
