How can I add some tabs??

I create a new Frame, then a wxNotebook with 2 pages, add some things on every page, and save it. It runs great, but when I open it again with the Frame designer, boa crashes:

(python:1968): Gtk-WARNING **: Can't set a parent on widget which has a parent
(python:1968): Gtk-WARNING **: Can't set a parent on widget which has a parent
(python:1968): Gdk-WARNING **: gdkdrawable-x11.c:952 drawable is not a pixmap or window
**
Gtk:ERROR:gtkcontainer.c:2743:IA__gtk_container_propagate_expose: assertion failed: (child->parent == GTK_WIDGET (container))
Aborted (core dumped)

What am I doing wrong?
