After some investigation, it seems that setting the
HildonTouchSelector widget to be in HILDON_UI_MODE_NORMAL causes
"changed" to exhibit the above behavior.

I now have a new problem.  When calling
hildon_touch_seletor_select_iter, the "changed" signal is emitted but
hildon_touch_selector_get_last_activated_row does not reflect the
newly selected row.  Any ideas?
