Ajax parseError() missing ?

Ajax parseError() missing ?

jq.1.3.2.js
3579# 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 (e) {
3585# status = "parsererror";
}
}
Currenlty above in case of (3585#) status = "parserror" , actual
exception information is lost. This is for both XML and JSON types.
Maybe having something like this :
$.ajaxSetup( { parseError : function ( evt, xhr, error ) {
alert( "parse error on ajax data returnded: " + e.description ) ;
} }) ;
would help ?
