Bug ID: 429027
Summary: System Settings segmentation faulted in
std::__atomic_base<QObjectPrivate::ConnectionData*>::l
oad when selecting Regional Settings
Product: systemsettings
Version: 5.20.2
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: matthew.fagn...@utoronto.ca
Target Milestone: ---
Application: systemsettings5 (5.20.2)
Qt Version: 5.15.1
Frameworks Version: 5.75.0
Operating System: Linux 5.9.8-200.fc33.x86_64 x86_64
Windowing system: Wayland
Distribution: Fedora 33 (KDE Plasma)
-- Information about the crash:
- What I was doing when the application crashed:
I was using Plasma 5.20.3 on Wayland in Fedora 33 with KF 5.75.0, Qt 5.15.1,
Mesa 20.2.2 in Fedora 33. I started System Settings. I selected Startup and
Shutdown > Login Screen (SDDM). I set the sddm background to Breeze because the
default Breeze Fedora showed a white sddm background after logging out of
Plasma. I selected various items on the menu on the left. System Settings
segmentation faulted in
std::__atomic_base<QObjectPrivate::ConnectionData*>::load when I selected
Regional Settings.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
