JQuery adds some weird string to the provided data

Code for reproducing the error (put the following code on the html page and read the data presented in Fiddler. JQuery 1.4.2 works fine, the problem occurs in 1.5.1 and 1.5.2):

<html>
<head>
<script src="https://github.com/douglascrockford/JSON-js/raw/master/json2.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script>
var data = { "Name": "test??", "testDesc": "testdesc??"};
  $.ajax({ 
    url: "submit.aspx/SubmitData", 
    data: JSON.stringify(data),
    type: "POST", 
    contentType: "application/json; charset=utf-8", 
    dataType: "json", 
    cache: false
  }).success(function (msg) {});
</script>
</head>
<body></body>
</html>

I am using jQuery 1.5.1 to process data and send data to the server

function test(name, testDesc){
  var data = { "Name": name, "testDesc": testDesc};
  $.ajax({ 
    url: "submit.aspx/SubmitData", 
    data: JSON.stringify(data),
    type: "POST", 
    contentType: "application/json; charset=utf-8", 
    dataType: "json", 
    cache: false
  }).success(function (msg) {//......});
}

Among the thousands of records, there are several records with a string like "jQuery151023383707909744822_1301931324827" and "jQuery151033911434971578497_1301989384660" in the data.

Is this a jQuery bug or any plugins that cause the problem?
