You must call gtk_widget_show() on widgets that you want to be visible
(or set the visible property to true in glade)... or call 
gtk_widget_show_all()
on some parent in the heirarchy (that may be the problem).

Hmmm seems that you are leaking the liststore every time, unreffing
it here should pass ownership of the model to the treeview... so that
next time you set the model the last model will be finalized.
