I have a suspicion. Here is how to system works:

event = AnyObjectEvent(obj)
-> zope.event.notify(event)
-> zope.app.objectevent.objectEventNotify(event)
-> subscribers((event.object, event), None)
-> yourHandler(obj, event)

Any IObjectEvent gets handled by objectEventNotify, which in turn sends out 
another subscription request for (obj, event). And you probably have a 
subscriber for the latter. The easy way to test this would be to manually 

  >>> yourHandler(event.object, event)
