Xinha fails to complete or crashes browser when 'Equation' plugin used

Site: web.missouri.edu/~johnsong/xinha/xtest.htm
Xinha revision: both 0.931 and the nightly from 20070717.
Javascript error: XinhaCore.js (line 5387), el has no properties

Remove 'Equation' and all seems well! Firefox safe mode does not help. Changing from a Windows to a Linux Apache server does not help.  IE 7.0.5730.11 displaysthe editor bars and allows a little typing in the text area, then crashes.

Firebug console traceback for Firefox 2.0.0.5 follows...

   * The list of plugins below is a good starting point, but if you prefer
   * a must simpler editor to start with then you can use the following
   *
   * xinha_plugins = xinha_plugins ? xinha_plugins : [ ];

   *   xinha_editors['myTextArea'].registerPlugins(['Stylist','FullScreen']);
   *   xinha_editors['anotherOne'].registerPlugins(['CSS','SuperClean']);

  /** STEP 5 ***************************************************************
   * If you want to change the configuration variables of any of the

   * change the width and height of one of the editors, like this...
   *
   *   xinha_editors.myTextArea.config.width  = '640px';
   *   xinha_editors.myTextArea.config.height = '480px';
