Well, the errors we're getting in serverlog strongly implied that somehow it was getting called with something null on MIT's site...

What I discovered after I pulled this patch was that it is not in fact the case that it's only called from ajax_tools.js. MIT had a template override on the homepage that called it directly. And it didn't even call it correctly. That would have certainly caused the errors that we're seeing, one every time anyone tried to log in on the homepage. Should be fixed now.
