This error comes from gtk, other gtk apps should give the same error. There's
some more info here:

https://unix.stackexchange.com/questions/145167/gnome-programs-eog-gnome-terminal-have-a-slow-start-and-produce-a-dbus-error-n

I'm guessing users who are seeing that are launching virt-manager over ssh -X,
to a machine which doesn't have any desktop user logged in, so the
accessibility daemon wasn't autostarted.

But it isn't something we can fix in virt-manager, it's just gtk being noisy
about a missing service.
