I've recently encountered an odd problem. My interface is build with glade, and I am using PyGTK/PyGnome under RH7.1 (Ximian Gnome 1.4). I have a GtkNotebook with 3 pages. I recently attempted to add a 4th page. Everything is fine, until the program exits, at which time I get the following error messages, followed by a crash: Gtk-CRITICAL **: file gtkobject.c: line 1162 (gtk_object_ref): assertion `GTK_IS_OBJECT (object)' failed. Gtk-WARNING **: invalid cast from `(unknown)' to `GtkObject' Gtk-WARNING **: invalid cast from `(unknown)' to `GtkObject' Gtk-WARNING **: invalid cast from `(unknown)' to `GtkObject' Gtk-WARNING **: invalid cast from `(unknown)' to `GtkObject' Gtk-WARNING **: invalid cast from `(unknown)' to `GtkObject' Deleting the 4th page of the notebook makes this go away. Interesting enough, if I view the 4th page, I get no errors, and everything is just fine. If I fail to view the page, I get the above errors and a crash. It doesn't matter what is on the page. If the page contains nothing but a label, it still crashes. Any ideas? _______________________________________________ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk
