Unity 5.2.1 Build crash on Application.Quit(); with Windows Touch

Hi,

I am upgrading my Unity 4 project to Unity 5.2.1. I have used Application.Quit(); to close the app on a button click. This worked fine earlier(Unity 4) and now (Unity 5.2) also works fine with mouse click. But if I click the button using Touch (on Windows 8 or Windows 7 Touch screens) the app crashes.

Then I tested by creating a new Unity project and added the attached file (rename the .txt to .cs) link text to the main camera. When I click this button with Touch it crashes. But doesn't crash with the mouse click. Is this a bug in Unity 5.2.1? How can I fix this issue?

Thanks

  if (GUI.Button(new Rect(10, 10, 50, 50), btnTexture))
         {
             Debug.LogError("Clicked the button with an image");
             Application.Quit();
         }
