What steps will reproduce the problem?
1. Create a serializable Dictionary<string, List<MyClassType>>
2. Serialize it
3. Deserialize it.

What is the expected output? What do you see instead?
Expected output is Serializer.Deserialzie to fill in the saved dictionary into 
a null Dictionary of the same type. (I'm using a class as a wraper)

What version of the product are you using? On what operating system?
win 8.1.
version rotobuf-net r668
