You shouldn't be emitting that signal directly. You should use the
notebook.set_page(page_num) method (which will emit "switch_page" if
appropriate). The signal takes a pointer argument to a GtkNotebookPage
struct (which shouldn't even be used in C programs these days ...) which
you can't create in Python, which is the cause of the exception.
