*Now, using the TreeModel and passing iterators, I get a shed load of
Gtk-CRITICAL **: 12:24:08.859: gtk_tree_store_get_path: assertion
'iter->user_data != NULL' failed interspersed with my own debug report of
invalid iters passed to on_combo_changed() I don't think this is connected
with the coupling. If I comment out the forward coupling call it makes
little difference. I've also tried calling unset_active() before the
clear() but it didn't help.*

```
G_DEBUG=fatal-criticals gdb ./your_exe
run
bt
