It then connects a signal handler to have on_button_press() called the
next time the selection changes.  That's a bit odd.

If you mean that on_button_press() sets the text on a label, it will do
so only on the second selection change.  On the third selection, it will
be called twice though, and three times on the fourth selection, and so
on.

If this is indeed copied from the tutorial, it needs to be fixed.  Where
exactly did you find it?
