Hey Tristan. Thanks for both suggestions. This first one I don't know
how to do because the GtkAssistant is being created by glade, and unless
there's some kind of Python magic I could rely on, I don't know of an
easy way to subclass it when it is already instantiated.

'b' is definitely a hack, but it might do the trick if I can get it to
work. I am trying the following,

        assistant.stop_emission("apply")

, except that the assistant still advances to the next page regardless.
Hmm...
