A gtk.Label does not have a gdk window (as in the windowing system of gtk+), 
so it cannot listen to events. A workaround is to put it in an eventbox:

eventbox = gtk.EventBox()
eventbox.set_events(gtk.gdk.BUTTON_PRESS_MASK)
eventbox.connect('button-press-event', callback)

label = gtk.Label()
eventbox.add(label)

notebook.append_page(..., eventbox)

Perhaps you should subscribe to the PyGTK mailing list[1] though, where this 
kind of question is more appropriately asked
