Not tested, but try these changes:

Change this function to:
def addbutton(widget):
     button = gtk.Button('extra')
     button.show() # Don't know if it really is needed here
     vbox.pack_start(button)
>      b1 = gtk.Button('aaa')
>      b1.connect('button_press_event', addbutton)
Connect to the gtk.Button's clicked signal, not the gtk.Widget's button 
press event. So:
b1.connect('clicked', addbutton)

Cheers,
Timo
