Application: plasmashell (5.18.5) Qt Version: 5.13.2 Frameworks Version: 5.73.0 Operating System: Linux 5.8.13-100.fc31.x86_64 x86_64 Windowing system: X11 Distribution: Fedora 31 (KDE Plasma) -- Information about the crash: - What I was doing when the application crashed: It just happens after a fresh restart. The only "weird" thing I've done recently was to install VMware Player, and I was able to see that it installed some "kernel modules". I've uninstalled it, but still the same. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

I think I might have solved it by installing "qt5-qtdeclarative-5.13.2-1.fc31.i686". I did it because I saw in the Backtrace some messages saying "at /lib64/libQt5Quick.so.5", and found that this is some library from the package qt5-qtdeclarative, tried to reinstall but then dnf said that the package wasn't installed. So, I installed it, rebooted, and so far it hasn't failed again.
Yes, that's a requirement for Plasma to work properly. :) If your distro didn't mark this as a dependency, you should file a bug on them to improve their Plasma packaging.
