Bug ID: 376042
Summary: Systemsettings crash when pressing the back button
Product: systemsettings
Version: 5.9.0
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: sakisd...@gmail.com
Target Milestone: ---
Application: systemsettings5 (5.9.0)
Qt Version: 5.8.0
Frameworks Version: 5.30.0
Operating System: Linux 4.9.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
Occasionally the systemsettings app will crash on exit or when exiting. Doesn't
happen every time but I haven't been able to pinpoint it to a specific KCM.
I am using the latest systemsettings package from Arch's repositories (5.9.0-1)
with the open source AMDGPU driver.
The crash can be reproduced sometimes.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
