[pygtk] Error message

[Frédéric]

I make my GUI with galde-3, and for one of them, when I create it with:

    self.wTree = gtk.glade.XML(gladeFile)

I get the following error:

/usr/local/lib/python2.4/site-packages/papywizard/view/configDialog.py:74:
GtkWarning: gtk_tree_row_reference_new: assertion `GTK_IS_TREE_MODEL
(model)' failed
  self.wTree = gtk.glade.XML(gladeFile)

/usr/local/lib/python2.4/site-packages/papywizard/view/configDialog.py:74:
GtkWarning: gtk_cell_view_set_displayed_row: assertion
`GTK_IS_TREE_MODEL (cell_view->priv->model)' failed
  self.wTree = gtk.glade.XML(gladeFile)

Any idea of the problem(s)?

I an send the .glade file if needed...
