[Ironruby-core] Bug in mscorlib, IronRuby, NewtonSoft.json..... or my code?

Hi,

I''m trying to use a third party library which has a dependency on
NewtonSoft.json. I create a class within IronRuby and attempt to
serialise the object to Json however it throws a null reference
exception from within mscorlib.

Any ideas?? Example is below:

Thanks

Ben

class Company
  attr_accessor :Name, :Id
end

c = Company.new
c.Name = ''test''


require ''Newtonsoft.Json''
include Newtonsoft::Json
JsonConvert.serialize_object c


mscorlib:0:in `Equals'': Object reference not set to an instance of an
object. (System::NullReferenceException)
        from mscorlib:0:in `IndexOf''
        from mscorlib:0:in `IndexOf''
        from mscorlib:0:in `IndexOf''
        from Newtonsoft.Json:0:in `CheckForCircularReference''
        from Newtonsoft.Json:0:in `SerializeList''
        from Newtonsoft.Json:0:in `SerializeValue''
        from Newtonsoft.Json:0:in `SerializeISerializable''
        from Newtonsoft.Json:0:in `SerializeValue''
        from Newtonsoft.Json:0:in `SerializeISerializable''
        from Newtonsoft.Json:0:in `SerializeValue''
        from Newtonsoft.Json:0:in `WriteMemberInfoProperty''
        from Newtonsoft.Json:0:in `SerializeObject''
        from Newtonsoft.Json:0:in `SerializeValue''
        from Newtonsoft.Json:0:in `WriteMemberInfoProperty''
        from Newtonsoft.Json:0:in `SerializeObject''
        from Newtonsoft.Json:0:in `SerializeValue''
        from Newtonsoft.Json:0:in `SerializeISerializable''
        from Newtonsoft.Json:0:in `SerializeValue''
        from Newtonsoft.Json:0:in `Serialize''
        from Newtonsoft.Json:0:in `SerializeInternal''
        from Newtonsoft.Json:0:in `SerializeObject''
        from Newtonsoft.Json:0:in `SerializeObject''
        from (ir):1

make the class backed by a real .NET Type not a ruby type and the serializer
will work again

I''m halfway through a library which serializes dynamic types to JSON. I
guess that should work in this case; I''ll post when it''s done.

Cheers,
Mark
