title: Error when reading from mailbox
body: <p>My application, created today, runs fine when I use it with my account. On any other account however, the following error is sent back as a response:</p>
  
  <pre><code>message: "(#298) You must be a developer of the application"
  type: "OAuthException"
  </code></pre>
  
  <p>The exact code I'm using to send the request is this:</p>
  
  <pre><code>FB.api('/me/threads', {limit: 1000}, function(response){ ....
  </code></pre>
  
  <p>I have found someone experiencing the same problem, but the response he accepted didn't really provide any useful information. ( <a href="https://stackoverflow.com/questions/7394374/reading-over-inbox-i-get-error-298">Reading over inbox, I get error #298</a>). </p>
  
  <p>Anyone have a clue on how to solve this? Would be greatly appreciated!</p>
