title: Publish Actions and Share on Facebook Page at the same time is not working
body: <p>We launched Facebook Timeline integration some days ago. Further to our users' feedbacks, I have a question. It's quite amazing, but this is what I found: </p>
  
  <p>When I do a "publish_action" almost at the same time as a "Share on Facebook Page" (with the same URL to share), I see that my "Share on Facebook Page" does not work and I get the following error:</p>
  
  <pre><code> Facebook responded with HTTP status code 400 and response body: 
   {"error":{"message":"(#1500) The url you supplied invalid","type":"OAuthException","code":1500}}
  </code></pre>
  
  <p>When the "Share on Facebook Page" is made after the "publish_action" (by after, I mean 30sec), it's working like a charm.</p>
  
  <p>The URL is indeed valid (just because the "publish_action" is well working)</p>
  
  <p>Do you have any idea about that ?</p>
  
  <p><em><strong>MAY 3 UPDATE</em></strong></p>
  
  <p>I've created a bug on facebook: <a href="https://developers.facebook.com/bugs/284272281663170" rel="nofollow">https://developers.facebook.com/bugs/284272281663170</a>
