[pygtk] libglade tree problems

[Rob Brown-Bayliss]

As my app starts I get these warnings:

test.py:52: GtkWarning: gtk_tree_row_reference_new: assertion
`GTK_IS_TREE_MODEL (model)' failed
  self.wtree = gtk.glade.XML("./test.glade") # Main glade xml file
test.py:52: GtkWarning: gtk_cell_view_set_displayed_row: assertion
`GTK_IS_TREE_MODEL (cell_view->priv->model)' failed
  self.wtree = gtk.glade.XML("./test.glade") # Main glade xml file

and I am curious as to why and what they mean?  Any ideas?  The app
runs fine apart from other bugs of my own design ;-)
