Bug ID: 456945
Summary: SystemSettings5 crash on sudo
Product: systemsettings
Version: unspecified
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_colors
Assignee: plasma-b...@kde.org
Reporter: alexcode...@gmail.com
CC: noaha...@gmail.com, tantalising...@gmail.com,
uhh...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.20.5)
Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.0-16-amd64 x86_64
Windowing system: X11
Distribution: Debian GNU/Linux 11 (bullseye)
-- Information about the crash:
- What I was doing when the application crashed:
I logged in to an user account and did sudo systsemsettings5, because I wanted
to have dark mode in sudo applications because they are always light mode. I
changed general theme, and closed the windows.
- Unusual behavior I noticed:
When clicking Apply button, nothing happens, I still have dark mode.
The crash can be reproduced every time.
-- Backtrace:
Application: Configuration du système (systemsettings5), signal: Segmentation
fault
