I believe this is your problem. Looking at Closures[1], GLib does not
ship with a marshaller that "understands" that signal's signature.

Run glib-genmarshal[2] and use "VOID: STRING, STRING, DOUBLE" as the
marshaller specification. Remember to call
dbus_g_object_register_marshaller[3] (I believe it should be done
before calling dbus_g_proxy_add_signal).

The section "GLIB with C examples" of
http://web.archive.org/web/20080501043040/http://wiki.bluez.org/wiki/HOWTO/DiscoveringDevices
may also be of help.
