Why am I getting a parseerror when using jQuery's ajax()?

Can someone tell me why in the world I keep getting a parseerror in the console with the following code?

$.ajax({
    url : "file.php",
    data : data,
    dataType : "json",
    success : function (request) {
        console.log("success");
    },
    error : function (request, error) {
        console.log(error);
    }
});

I have validated my JSON with jsonlint.com and it's Valid.

The Response Headers being returned in the Net tab of Firebug are:

Content-Length 19

Keep-Alive timeout=5, max=96

Connection Keep-Alive

Content-Type application/json

This is how you can send json from PHP

$response = array("title" => "One");

echo json_encode($response);

If { "title": "One" } is the response, Content-Length of response should be 18, but from your description I can see that it is 19. So something is wrong in the response json string, please check it.

It seems possible that the name or value of this may have invalid characters. Instead of concocting your own data string how about letting jQuery do it for you:

data  = $this.serialize();
