title: Jquery get data on XHR error
body: <p>If I make a jquery AJAX request which is succesful I get back my JSON data. However, If I make a request and I get somthing other than a 200 response code back, I cannot get back the data in the Jquery call back. I need the data as it has a description about the data.</p>
  
  <pre><code>success: function (data, tst, xhr) {
      $.log('XHR OK');
  },
  error: function (xhr, tst, err) {
      $.log('XHR ERROR ' + XMLHttpRequest.status);
  },
  </code></pre>
  
  <p>Any ideas?</p>
  
  <p>Thanks</p>
