Bug ID: 441449
Summary: KDE System Settings crashes reproducibly when
selecting "Appearance" (among other elements)
Product: systemsettings
Version: 5.22.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: koslow...@kofo.mpg.de
Target Milestone: ---
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.
