This is a guess, but I would suggest that the selection and the cursor 
are not the same thing, and thus changing the selection does not 
necessarily change the cursor. If you want to catch selection changes, 
use Gtk::TreeSelection::signal_changed() which works if you set the 
selection via code, or via clicking on the TreeView, using the keyboard 
or whatever.
