Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

-- Information about the crash:
Steps to Reproduce:
1. Open System Settings > Appearance > Global Theme
2. Select a different theme than the current (for this crash, I selected Breeze
Dark IIRC)
3. In the "Apply Breeze Dark" dialog, check [x] Appearance settings and [x]
Desktop and window layout
4. Click [ Apply ] button
Expected Results:
1. Theme should be applied as selected.
2. System settings should not crash.
Actual Results:
1. Theme is applied as selected (Good!)
2. System settings crashes (BAD)
This behamatches closed bug 458405 which is marked as a duplicate of bug
446111. However, I have been able to reproduce, and the failure mode may vbe
different. This is also on Plasma 5.27.2.
Frequency: Estimated below 5%. While this crash occured once, I tried 20
additional times using the same system settings instance each time, and it
occurred again on the 20th attempt. The detail listed is:
Executable: systemsettings PID 50,622 Signal: Segmentation fault (11) Time
3/1/23 5:27 PM
The reporter is unsure if this crash is reproducible.
