Well. I know what the problem is, I just can't figure out what is causing it.
standard_text_editor.js:29 TypeError: Result of expression 'get_object(menus[i])' [null] is not an object.
i is being set to "filter" somehow. I've looked at the twitter code and can't figure it out, but I'm not a ninja. Maybe SD or Gizmo can take a crack.
