My code was something like this:

var cancel; 
//... bla bla
cancel = form.elements[i]; //cancel is now a ; no Id, unique on the page
cancel.addEvent('click', function(e) {...});

And I was getting the OP's exception on cancel.AddEvent(). What fixed it for me was rewriting that as $(cancel).addEvent().

What a horrible browser.
