I'm implementing the Facebook SDK in my Unity-created game and I'm having a lot of problems. I tried to implement the Facebook login system:

FB.LogInWithReadPermissions(new List<string>() { "public_profile", "email", "user_friends" }, AuthCallBack);

Only the following errors appeared:

NullReferenceException: Object reference not set to an instance of an object

Sorry to answer in English, but I had the same issue and Facebook is already aware of the bug: link

They have a temporary workaround: in EditorFacebookMockDialog.cs add this to the begin of the OnGUI method:

if (this.modalStyle == null)
{
    this.modalRect = new Rect(10, 10, Screen.width - 20, Screen.height - 20);
    Texture2D texture = new Texture2D(1, 1);
    texture.SetPixel(0, 0, new Color(0.2f, 0.2f, 0.2f, 1.0f));
    texture.Apply();
    this.modalStyle = new GUIStyle(GUI.skin.window);
    this.modalStyle.normal.background = texture;
}

It should end up like this:

public void OnGUI()
{
    if (this.modalStyle == null) {
        this.modalRect = new Rect(10, 10, Screen.width - 20, Screen.height - 20);
        Texture2D texture = new Texture2D(1, 1);
        texture.SetPixel(0, 0, new Color(0.2f, 0.2f, 0.2f, 1.0f));
        texture.Apply();
        this.modalStyle = new GUIStyle(GUI.skin.window);
        this.modalStyle.normal.background = texture;
    }
    GUI.ModalWindow(
            this.GetHashCode(),
            this.modalRect,
            this.OnGUIDialog,
            this.DialogTitle,
            this.modalStyle);
}

They say they are going to fix this for the next update
