I *knew* I'd done something wrong, its one of the things I do best. :-)

#ifdef G_ENABLE_DEBUG
	if (!CORBA_Object_is_a (BONOBO_OBJREF (object),
				"IDL:Bonobo/Unknown:1.0", NULL))
		g_error ("Attempt to instantiate non-Bonobo/Unknown "
			 "derived object via. BonoboObject");
#endif

So right now this causes failures in programs that initialize Bonobo,
which is a bad thing... The problem is (as you said) creating the
MonikerContext object. It looks like what is happening is that
object->corba_objref is NULL, which is of course causing
CORBA_Object_is_a to harf when BONOBO_OBJREF consequently returns NULL.
Is this happening too soon (i.e. before all the corba stuff is connected
together) or is something unusual about the monikercontext object? I
don't know enough about Bonobo internals etc to really be able to push
farther I think.
