Application: systemsettings5 (5.15.2) Qt Version: 5.12.0 Frameworks Version: 5.55.0 Operating System: Linux 4.15.0-46-generic x86_64 Distribution: KDE neon User Edition 5.15 -- Information about the crash: "Sytem settings" hangs when trying change the loading screen and saving it. (System language is Russian) - What I was doing when the application crashed: Tried to close a window, then my Neon killed it itself, then I restarted ''System settings" . The windows worked, but when I tried to repeat changing the loading screen, the bug repeated too. The crash can be reproduced every time. -- Backtrace: Application: Параметры системы (systemsettings5), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
