@marmarek, any suggestions on who should review this?

This is interesting because this doesn't work for me in 2 R4.1 installations, using fedora-37-xfce or fedora-38-xfce. Without sudo it's working fine, with sudo it's failing with `failed to execute child process "dbus-launch" (no such file or directory).

Should I open an issue about this?

This works in a Debian 11 Qube though.

@rapenne-s: I'm not sure if it's a bug, but if it is, it sounds like it could be a bug specific to the Fedora XFCE template. If so, that'd merit an issue, I reckon.
