 Not found either, but screensaver works fine here.

 grep org.gnome.GkbdConfigRegistry -r /usr/share/dbus-1/services

 I don't get this.

 It builds fine in a pbuilder here; I fear you have been bitten by
 #410106.

 Interesting.

 I think the problem is that some program crashes or exits with your
 keyboard layout; I don't know which, but usually it's
 gnome-settings-daemon: could you run "ps fauxwwwww | grep
 gnome-settings"?

 I think it spawns stuff which is supposed to provide the service you
 mentionned.  I think .service files are only necessary for
 autospawning.
