title: Handling facebook exceptions
body: <p>maybe it is simple, but i do not know how to do it, so i ask.
  Sometimes i get an exception from facebook e.g. posting an action has failed. Normally it works but sometimes dont. I use the php sdk and when there is sth. wrong i get an facebook exception and the whole site stops running. </p>
  
  <p>Is there a way i can ignore these exceptions and store it in database instead, so that the rest of the website works?</p>
  
  <p>I think it is in the base_facebook.php, hopefully someone knows what line i must change.</p>
  
  <p>Thank you very much</p>
