Re: Custom Class Serialization with Serpent.

Hey Irmen,
                 I agree that the problem lies with the deserialization. But should the same behavior happen when I am not using IPAddress? Rather, I am using a custom class composed of primitives, if you may call them that. I see the deserialization error even on a class that contains just integers and strings.

Regards,
Abhishek.

P.S : And I will definitely take a look at building something. :) (if my limited knowledge of Python permits)
