GtkNotebook

[Leo Przybylski <leo leosandbox org>]

Hello all,

I'm trying to create a GtkNotebook. Whenever I use 
gtk_notebook_append_page, I get the error:

(console:23209): Gtk-CRITICAL **: file gtkbindings.c: line 580 
(gtk_binding_set_by_class): assertion `GTK_IS_OBJECT_CLASS (class)' failed

(console:23209): Gtk-CRITICAL **: file gtkbindings.c: line 765 
(gtk_binding_entry_add_signal): assertion `binding_set != NULL' failed

It seems to hit right when I make the call to gtk_notebook_append_page. 
I'm using the example right out of the Gtk-2.0 Tutorial. I haven't 
changed anything.

Anyone have any idea what this is?
