Error: A valid UTF32 value is between 0x000000 and 0x10ffff when getting result

I am getting an error when I hit a specific post in Facebook:

Here is the code to run: Just replace to token with yours...

FacebookClient client = new FacebookClient(yourTokenHere);
var result = client.Batch(
                new FacebookBatchParameter(HttpMethod.Get, "/198907640664_196037430420783"),
                new FacebookBatchParameter(HttpMethod.Get, "/198907640664_196037430420783/comments", new Dictionary<string, object> { { "limit", 20 } }) { Data = new { name = "myposts", omit_response_on_success = false } }
            );

The error received is:

Error: A valid UTF32 value is between 0x000000 and 0x10ffff, inclusive, and should not include surrogate codepoint values (0x00d800 ~ 0x00dfff). Parameter name: utf32

The stack trace is:

System.ArgumentOutOfRangeException: A valid UTF32 value is between 0x000000 and 0x10ffff, inclusive, and should not include surrogate codepoint values (0x00d800 ~ 0x00dfff).

I do get this error with other calls as well.

Thanks in advance for any help.

Just found out that Prabir (The Man of the Facebook C# SDK) have released a new version of SimpleJson v0.7 containing this bug fix. http://simplejson.codeplex.com/releases/view/69446

and also updated the SimpleJson in Facebook C# SDK to v0.7 http://facebooksdk.codeplex.com/SourceControl/changeset/changes/4f05d3ba8c17

I have tried it and it works fine!

Thanks Prabir
