Bug ID: 408709
Summary: system settings crashed on Wayland when I was
switching between the sections of "Desktop behavior"
Product: systemsettings
Version: unspecified
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: bugsefor...@gmx.com
Target Milestone: ---
Application: systemsettings5 (5.16.80)
Qt Version: 5.12.3
Frameworks Version: 5.60.0
Operating System: Linux 4.18.0-21-generic x86_64
Distribution: KDE neon Unstable Edition
-- Information about the crash:
- What I was doing when the application crashed:
I opened system settings > desktop behavior
and system settings crashed after I click almost all sections in the left side,
from top to bottom. I think that system settings crashed when I reached
"Virtual desktops".
The crash can be reproduced every time.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
