Re: Cross-coupling comboboxes

[Rob Pearce <rob flitspace org uk>]

Thanks, it seems to work. At least, mostly...

One of the other changes I'm making needs me to test an existing bit of 
functionality which replaces the underlying "stuff". This means that the 
TreeModel content is clear'd then re-built. With the simple list and 
ComboBoxText, this worked fine. 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.

Any ideas?
