Cool.  Are you using 0.33?  Latest CVS?  Or CVS + my latest patch?

The client side of signals should work...there's a test in
test/glib/test-dbus-glib.c, however I want to change the API soon to
remove the D-BUS types.  

However as you've discovered, it looks like the server side is not
implemented.  I hadn't noticed that before now, I've been mainly working
on method invocations.

Yeah.  Until we fix the bindings this is the workaround.  It should not
be too difficult to implement; from a quick look at the GObject signal
API, inside dbus_g_connection_register_g_object, we'd iterate over the
object's signals, use g_signal_add_emission_hook to add a callback.
Inside that callback we would iterate over the GValues and marshal them
to a D-BUS message using dbus_gvalue_marshal.
