Ah, I guess you are the first to test this.

The Gtk::TreeModelFilter constructor needs to do the same as
gtk_tree_model_filter_new(). Normally those _new() functions should just
pass the parameters to g_object_new(), but this one does some extra stuff
that we can't do from outide.

I think this will need an API addition in GTK+, to add a _construct()
function, so it's unlikely that this will be working in gtkmm until gtkmm
2.5/2.6. I will work on that. For now, you could try using the C functions
directly, with gobj() and Glib::wrap().
