I know you have now solved this, but one thought that this prompts is whether 
your problems may have been partly connected with using a Gtk::TreeModelSort 
object to wrap a Gtk::TreeSortable object to use with Gtk::ListStore.  
Gtk::ListStore is already sortable: it uses multiple inheritance and inherits 
from, amongst other things, Gtk::TreeSortable.
