Deferred objects (new in jQuery 1.5) sound like exactly what you're looking for:

jQuery.Deferred, introduced in version 1.5, is a chainable utility object that can register multiple callbacks into callback queues, invoke callback queues, and relay the success or failure state of any synchronous or asynchronous function.

EDIT:

The following code works fine for me:

function jsonError(){
    $("#test").text("error");
}

$.getJSON("json.php",function(data){
    $("#test").text(data.a);
}).fail(jsonError);

json.php looks like this:

print '{"a":"1"}';

The error function fires for me if the path to json.php is incorrect or if the JSON is malformed. For example:

print '{xxx"a":"1"}';
