Twitterizer TwittterTimeline NewtonSoft.JSON.JsonSerializationException problems

Question

The following code throws a NewtonSoft.JSON.JsonSerializationException {"Unexpected token when deserializing object: StartObject. Line 1, position 1884."}

Twitterizer version :2.4.0.26532 NewtonSoft.Json = 4.0.7.0 (installed using the Nu-GET add in in visual studio)

Is there something I'm missing or dont't get?

   class Program
    {
        static void Main(string[] _args)
        {
            Logger.Write("Calling Twitter", Constants.TWITTER_AGREGATOR_LOG_CATEGORY);

            UserTimelineOptions options = new UserTimelineOptions();
            options.ScreenName = "as_tuce2";
            TwitterResponse<TwitterStatusCollection> tweets = TwitterTimeline.UserTimeline(options);   //throws exception


            OAuthTokens tokens = new OAuthTokens();
            tokens.AccessToken = // removed...
            tokens.AccessTokenSecret = // removed...
            tokens.ConsumerKey =  // removed...
            tokens.ConsumerSecret = // removed...

            UserTimelineOptions userOptions = new UserTimelineOptions();
            userOptions.IncludeRetweets = false;
            userOptions.ScreenName = "as_tuce2";
            userOptions.UseSSL = true;
            userOptions.Count = 20;


            TwitterResponse<TwitterUser> showUserResponse = TwitterUser.Show(tokens, "as_tuce2");            //ok
            TwitterResponse<TwitterStatusCollection> timelineResponse = TwitterTimeline.UserTimeline(tokens);  //throws exception


            Console.ReadLine();
        }
    }

Thanks for posting this. I'll have to take a look at it and figure out what the new version of json.net changed.

For posterity, here is the forums topic where you reported the bug there, too.
