ADDITIONAL INFORMATION
Comment 1 Ali 2025-12-18 12:13:33 UTC
Can reproduce on the fedora native package, but NOT on the flatpak, this leads me to believe this is a packaging oversight on Fedora's end, which unfortunately has not been too uncommon on F43 :T, closing and setting as resolved/downstream unless anybody else can report it happening on other distros.
To the bug submitter, please report this to Fedora's bugzilla! ( https://bugzilla.redhat.com/ )

Just verified this also happens on a fresh Arch KDE install from a VM, same errors as mentioned above. My apologies for closing the bug prematurely.

This also happens on NixOS with native package ( kamoso 25.12.0 )

Running it with `sudo` or as root makes it work (albeit a wee buggy).
