button.set_active(True)

Note, this will cause the 'toggled' signal to be emitted for both the
button being unset and the the button being set. You should have a
toggled signal handler shared with each button in the group, then test
for whether the button in question is active, e.g.

    def radio_changed(self, radiobutton, choice):
        if radiobutton.get_active():
             # choice is the new button selected in the radio group
        else:
             # choice was unset, mostly you don't have to handle this

Note: choice is the user_data you pass in when you connect the toggled
signal to the button.
