can not unpack the IDictionary<string, string> in 0.4.3

[takekazuomi]

In MsgPack.Cli 0.4.3, I can not unpack the IDictionary<string, string>. It's works in the previous 0.4.2.

By pack such a class, then unpack

public class SomeOne
{
    public string Target;
    public IDictionary<string, string> Data;
}

It is an error such as:

Hi. Sorry for delay.

It is a bug related to interface type handling. I fixed it and released 0.4.4.
