Application: systemsettings5 (5.13.3) Qt Version: 5.11.1 Frameworks Version: 5.47.0 Operating System: Linux 4.14.55-1-lts x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: In system settings, select the Applications - Launch feedback pane. The title bar starts rapidly switching between having a star (indicating changed settings) and not. Selecting another tab/pane at this point will crash system settings. The crash can be reproduced every time. -- Backtrace: Application: System Settings (systemsettings5), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
