Description of problem:
probably nautilus under wayland
SELinux is preventing /usr/bin/totem-video-thumbnailer from 'write' accesses on the sock_file wayland-0.

*****  Plugin catchall (100. confidence) suggests  ***************************

If вы считаете, что totem-video-thumbnailer следует разрешить доступ write к wayland-0 sock_file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
чтобы разрешить доступ, выполните:
# grep totem-video-thu /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
