title: Strange error in usage story feed: This story was invalidated because
body: <p>Facebook was automatically publishing my application's usage story feeds. But I saw a strange error at app usage story feed panel tonight(At the right hand side of the screen). Which was:</p>
  
  <p>This story was invalidated because: The object at <a href="http://apps.facebook.com/onlinekullanicilar/" rel="nofollow">http://apps.facebook.com/onlinekullanicilar/</a> doesn't have a title.</p>
  
  <p>But my application do have title tags (both title and meta og:title elements)</p>
  
  <p>Any opinions?</p>
