  Yeah, I've run into the same problem in the past.  I ended up
connecting to the "set-frame" signal (copying EOG's example, I think). 
I'm not 100% sure that I'm doing the correct thing, but it works well. 
Here's my python handler for set-frame, and I'm sure you can easily
translate that to C:

    def __set_frame_cb(self, control):
	frame = control.get_control_frame()
	if frame is None:
	    uic = control.get_ui_component()
	    uic.unset_container()
	else:
	    ui_component = self.get_ui_component()
	    ui_component.set_container(self.get_remote_ui_container())
	    bonobo.ui.util_set_ui(ui_component, '',
				  gnumexp_conf.UIDIR + '/Numexp_Console-ui.xml',
				  'numexp-console')
	    verbs = [
		("ViewDefinitions", self.__view_definitions_toggle_cb),
		("Modules",         self.__modules_cb),
		("MathMLOutput",    self.__mathml_output_toggle_cb),
		]
	    ui_component.add_verb_list(verbs)
	    ui_component.connect('ui-event', self.__ui_event)
	    self._read_settings(ui_component)
