Every time I tried to install a collection of fonts, open or true type, I got a message that the font installer backend had crashed and was restarting. This continued even after logging off and logging back in. The crash can be reproduced every time. -- Backtrace: Application: System Settings (systemsettings5), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
