title: Monotouch Facebook Binding Publish to Wall crash
body: <p>I downloaded and build the facebook-binding from <a href="https://github.com/mono/monotouch-bindings" rel="nofollow">https://github.com/mono/monotouch-bindings</a>
  The authentication works, but when I try to post something to my wall I get native crashes.
  After the "Post to Wall" Dialog has shown up, the app crashes when I click "Cancel" and also when I click "Share". The actual post gets successfully posted to my wall, but the crash is not very amusing :)</p>
  
  <p><strong>Here is the native stacktrace:</strong></p>
