Javascript: How to stop multiple jQuery ajax error handlers?

Question

A team member put this into our project

$(function() {
    $("body").bind("ajaxError", function(event, XMLHttpRequest, ajaxOptions, thrownError){
        alert(thrownError);
    });
}

However I want to supress one of my errors (as it would be noise and verification isn't needed)

function blah() {

    ...

    errFunc = function(event, xhr, opts, errThrown) {
        //what could I do here?
        //event.stopImmediatePropagation()?
    }

    $.ajax({
        url        : '/unimportant_background_refresh',
        type       : 'GET',
        data       : { },
        dataType   : 'json',
        success    : updateBackgroundStuff,
        error      : errFunc,  // Suppresses error message.
    });

}

How can I stop the catch all error from happenning please? Can I just do something in the error function such as { event.StopPropogation(); } or must I work out some mechanism for having the catch all selectively ignore things please?

Global events can be disabled, for a particular Ajax request, by passing in the global option, like so:

 $.ajax({
   url: "test.html",
   global: false,
   // ...
 });
