Are you sure that there is void* partial specialization? What exactly
does it look like?

It works for RefPtr and for other random types. TreeModelColumn should
generate a custom gtype (via Glib::Value) to identify the type inside
TreeView so you shouldn't get that warning theoretically.

A little test case might help us figure it out. You could try it with
just a shared_ptr<int>, for instance.
