Absolutely right, thank you. I should have spotted that.  I think the
Gtk.TextView contructor used to take a buffer parameter but the
version 3 one doesn't so I had removed it. Hence, as you say, no code
tying them together.  I've simply changed to:-

    self.view = Gtk.TextView.new_with_buffer(self.buffer)

... and all is well again.
