jQuery validation plugin, Unable to get value of the property 'call'

jQuery validation plugin, Unable to get value of the property 'call'

Upgraded an application to version 1.9 of jQuery and 1.10 of jQuery UI using IE currently, if I set the Compatiablity tag to IE8 it is fine, but on IE 9 I get that error message when the jQuery validation plugin fires up.
 
In the last section of the jQuery Validation library where it does the cross browser support, actually $.event.handle is undefined, was all working ok with the previous version I was on, is this just a version
compatiability issue and I need to roll back ?

function handler(e) {
  e = $.event.fix(e);
  e.type = fix;

  return $.event.handle.call(this, e);
}
