Prevent people who somehow get a null element in the event cache from shooting themselves in the foot: This doesn't seem to happen often, but it has happened in internal code. I'm going to add more debugging info to  #440 as we get it, but want to get this in to prevent people from shooting  themselves in the foot in IE accidentally.<commit_after>/* Copyright (c) 2006 MetaCarta, Inc., published under a modified BSD license.
