Something that might shed light on this bug:
>From a normal terminal (or from ALT+F2) do: gksu xterm & It starts up xterm without any issues. Then from the xterm window do gnome-terminal & The following error message comes up: Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Process /usr/lib/gnome-terminal/gnome-terminal-server exited with status 1 Unsetting the DBUS_SESSION_BUS_ADDRESS does nothing to eliminate the problem.
