[Crash] Private chat

I clicked private chat because I wondered what it would do and

System.NullReferenceException: Object reference not set to an instance of an object.
   at ReadyToPlay.Forms.UniversalChatWindow..ctor(SelectableFriend oFriend, String strChannel)
   at ReadyToPlay.ChatManager.AddWindow(String strFriendName, String strChannelID)
   at ReadyToPlay.Forms.UniversalChatWindow._miPrivateChat_Click(Object sender, RoutedEventArgs e)
   at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs)
   at System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised)
   at System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args)
   at System.Windows.UIElement.RaiseEvent(RoutedEventArgs e)
   at System.Windows.Controls.MenuItem.InvokeClickAfterRender(Object arg)
   at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter)
   at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler)

that's what it does. Has the feature not been implemented yet or is this an actual problem?
