InvalidCastException when using Newtonsoft.Json.dll (10.0.1 .NET 4.0)

I get an uncaught exception of type System.InvalidCastException when I try to execute the following:

            // Load the document
            using (Stream strm = archive.GetFileStream("package.json"))
            {
                using (StreamReader reader = new StreamReader(strm))
                {
                    // The following line crashes!
                    dynamic rootObject = JsonConvert.DeserializeObject(reader.ReadToEnd());
                }
             }

The generated JSIL line that causes the crash somewhere in the NewtonSoft.Json.dll js code looks like this:

var rootObject = $T0D().DeserializeObject(($S05().Construct(strm)).ReadToEnd());

Exception message in log div:

Unhandled exception at http://127.0.0.1/web/Libraries/JSIL.Core.js line 5034:
Uncaught System.InvalidCastException: Unable to cast object of type 'Newtonsoft.Json.JsonTextReader' to type 'Newtonsoft.Json.Serialization.TraceJsonReader'.

Edit: The C# code runs just fine in a compiled Windows application, so the JSON data isn't corrupted. Edit 2: I also checked in the javascript debugger that the stream contains the correct json text value, so everything got loaded correctly from the local file storage.

I have the same problem (using Newtonsoft.JSON 7.0.1, because modern ones do not even compile for JSIL). I am trying to call a C# method from JS like this

// index.html JS
window.asm = JSIL.GetAssembly("myproject", true);

// C#
private Dictionary<string, object> dict;
public MyClass(string json) {
    this.dict = Newtonsoft.Json.JsonConvert.DeserializeObject<Dictionary<string, object>>( json );
}

// Then in the browser console I try to instantiate MyClass
asm.mynamespace.MyClass(JSON.stringify({a:1, b: "hello"}))

This creates the same error message as shown by Kyoril: Unable to cast object of type 'Newtonsoft.Json.JsonTextReader' to type 'Newtonsoft.Json.Serialization.TraceJsonReader'. Stacktrace:

@Kyoril Did you find a workaround?
