Can no longer serialise Vector3[] as RPC parameter

Just updated to latest PUN (Free, via Asset store) 1.50.1. I was a few versions out of date so I'm not sure when this problem was introduced.

I can no longer send a Vector3 array as a parameter on an RPC call. I reproduced the problem in the Marco Polo demo as follows:

In RandomMatchmaker.cs I added the following: 
...
            if (shoutMarco && GUILayout.Button("Marco!"))
            {
                myPhotonView.RPC("Marco", PhotonTargets.All);

                Vector3[] test = new Vector3[1] { new Vector3(1, 1, 1) };
                myPhotonView.RPC("Test", PhotonTargets.All, test);
            }
...

In AudioRpc.cs, I created a blank RPC method: 
...
    [RPC]
    public void Test(Vector3[] test)
    {

    }
...

When you click the Marco! button, the following trace is produced in the console: 
NullReferenceException: Object reference not set to an instance of an object

    I am also running into this problem and it has totally broken my game. I am trying to do the following ..
    Vector3[] waypoints = new Vector3[3];
        waypoints[0] = transform.Find("1").position;
        waypoints[1] = transform.Find("2").position;
        waypoints[2] = transform.Find("3").position;

        object[] data = new object[3];
        data[0] = waypoints;
        data[1] = transform.Find("1").position;
        data[2] = GetComponent<PhotonView>().viewID;
        PhotonNetwork.InstantiateSceneObject("CHICKEN", transform.position, Quaternion.identity, 0, data);

    This has worked flawlessly in the past, however upon updating to 1.50.1, it throws ..

    The error definitely has to do with using a Vector3 array. Any help would be appreciated!

    I will look into this asap but I guess the fix will take until next week.
    Sorry for the inconvenience.

    No problem - I've rolled back to previous version in the meantime.

    I got a fix for the next release. I missed updating the serialization methods for arrays of custom types.
    Should be out next week.
