When doing a method call from which you do not expect a reply, you need
to tell D_Bus that you don't expect a reply, which we're not doing here.
D-Bus recently got more restrictive about this.  It's not a functional
issue, just an annoying warning one.  But dbus-glib should be handling
this automatically since January 2009.  What version of dbus-glib do you
have?
