$.getJSON get silent error on retrieving data

I try to retrieve data from a JSon services but I have some problem and I'm not able to pass trough the debug process.

I retrieve data from this dynamique services : http://www.synergiescanada.org/json/otherpublicationbyid?synid=synergies:bcn.arbutus.215.3263 I validate the result with this tool http://jsonformatter.curiousconcept.com/ and it look fine.

[
   {
      "name":"Dr. Andre Smith",
      "publications":[
         {
            "id":"synergies:bcn.arbutus.215.3264",
            "title":"Exploring death and dying through discourse",
            "uri":"http:\/\/journals.uvic.ca\/index.php\/arbutus\/article\/view\/3264",
            "date":"2010-10-18"
         }
      ]
   }
]

But in another way when I use .getJSON method from jquery the it fail.

<script type="text/javascript"> 
$(document).ready(function() {
  $.getJSON("http://www.synergiescanada.org/json/otherpublicationbyid?synid=synergies:bcn.arbutus.215.3263" , 
    function(json) {
    alert(json);
  });
</script> 

The popup alert is never trigged and as I understand getJSON fail silently after having some king of error when he retrive my JSON data.

I try do debug with firebug I just found this into the Console about the headers

(sorry I can add image I'm new)

The same demo page trigger JSON api from flickr and it doesn't complain at all so it look as I miss something here. Maybe it's obvious.

If someone can give me a clue I'll appreciate.

Looks like a cross-site scripting issue -- your trying to get data from localhost of an external site. A workaround could be to use PHP as a "proxy." See: http://jquery-howto.blogspot.com/2009/04/cross-domain-ajax-querying-with-jquery.html
