Hello!

the switch page signal handler has got the following format:
on_notebook_switch_page (GtkNotebook     *notebook,
                         GtkNotebookPage *page,
                         gint             page_num,
                         gpointer         user_data);

where page_num is the number of the page switching to.
gtk_notebook_get_current_page() also gets the _current_ page, but the
current page when handling this signal is the _old_ page as the signal
handler is called before setting up the new page.

I guess another solution would be (i never tried this, so i might be wrong):
Use your old signal function with gtk_notebook_get_current_page() and
connect this handler with gtk_signal_connect_after() instead of
gtk_signal_connect();
