This will catch (among other things) cases when
gvir_config_object_get_xml_node() is called with a NULL argument. Not
catching this could cause a crash later on in cases when
gvir_config_object_new_from_xml() is called and returns NULL, and then
we call gvir_config_object_get_attribute() on it.
Now this should be caught with runtime warnings so that the underlying
issue can be fixed.
