What version of jQuery are you using?

If you check jquery's code, parsererror is thrown when jQuery.httpData() is called. Here's the code from jquery:

if ( status === "success" ) {
  // Watch for, and catch, XML document parse errors
  try {
    // process the data (runs the xml through httpData regardless of callback)
    data = jQuery.httpData( xhr, s.dataType, s );
  } catch(err) {
    status = "parsererror";
    errMsg = err;
  }
}

Maybe jQuery.httpData() is worth looking at. That is, you can check if jQuery.parseJSON is called and if it indeed returns an object.

if ( typeof data === "string" ) {
  // Get the JavaScript object, if JSON is used.
  if ( type === "json" || !type && ct.indexOf("json") >= 0 ) {
    console.log(data); //add this
    data = jQuery.parseJSON( data );
    console.log("data parsed successfully"); //add this
