QML ApplicationWindow blank when calling show after a previous close

Following code demonstrates the problem.

Once a Window is shown and closed, calling a show on it again renders a blank window.

import QtQuick 2.1
import QtQuick.Controls 1.0
import QtQuick.Window 2.0

ApplicationWindow {
  title: qsTr("Hello World")
  width: 640
  height: 480
  property ApplicationWindow win : ApplicationWindow {
    title: "hello"
    Button {
      text: "Something"
      anchors.centerIn: parent
    }
  }

  Button {
    anchors.left: parent.left
    text: "Open"
    onClicked: win.show();
  }

  Button {
    anchors.right: parent.right
    text: "Close"
    onClicked: win.hide()
  }
}

Steps to reproduce:

• Create a new Qt Quick UI project from Qt Creator
• Paste the above code into the qml file and run

Now showing the Window first time is fine.
If the opened window is hidden by using the Close button on the parent window, Calling show the second time shows the Window fine. However if you just close the Window directly from the Window chrome of the new window, calling show henceforth renders a blank Window.

PS:

This problem was also present in RC1_171 snapshot.

Just downloaded the RC1 dev release installer today. This problem is present and also the entire app at most times starts up blank. Just cleaning the entire project and re-running seems to make it work once or twice and the problem repeats itself.
