Cannot deserialize record with two fields of same CLI type

[vasily-kirichenko]

type T =
    { F1: IList<int>
      F2: IList<int> }

let t = 
    { F1 = [||]
      F2 = [||] }

let p = FsPickler()
let ms = new MemoryStream()
p.Serialize(ms, t :> obj)
ms.Position <- 0L
let p1: obj = p.Deserialize ms

result:

System.ArgumentException: An item with the same key has already been added.
