It appears to be registered as a GBoxed type, though.  That means you can put it 
in your 'maps' file and get the conversion stuff auto-generated for you.  And 
since UniqueMessageData seems to be opaque intentionally, the default GBoxed 
representation chosen by Glib::Boxed (opaque scalar reference) seems fine and 
you shouldn't need custom converters.

This happens because a signal apparently uses UniqueMessageData in its 
signature, so the generic signal marshaller in Glib complains that this type 
hasn't been registered with the bindings.  If you put UniqueMessageData in your 
'maps' file, this should just work.
