Almost certainly. The dbus-daemon is started on a per-greeter basis
(one per X11 or Wayland display) because on multi-seat or XDMCP systems,
gdm wants to run several independent sessions all sharing one uid; so it
can't talk to `systemd --user`.

The error message is different because gsd-sharing is still trying to
perform activation via autostarting, whereas gnome-session has been taught
not to try to do that (it won't work).

Ideally these messages shouldn't appear, but I don't think they indicate
a real bug.

In an ideal world, I suspect this service shouldn't even be started in
the greeter: there's no reason why the greeter session would want to
share anything with a LAN.
