title: "BUG segmentation fault" while working with private_pub gem
body: <p>I was trying the code from this screencast <a href="http://railscasts.com/episodes/316-private-pub" rel="nofollow">http://railscasts.com/episodes/316-private-pub</a>. I grabbed the code from github.
  However, whenever, I try to send a message from that app, the faye server shuts down giving following error:</p>
  
  <pre><code>/home/jatin/.rvm/gems/ruby-1.9.3-p362/gems/thin-1.3.1/lib/thin/connection.rb:105: 
  [BUG] Segmentation fault
  ruby 1.9.3p362 (2012-12-25 revision 38607) [i686-linux]
  </code></pre>
  
  <p>(It also displays long control frame information and stack trace information)</p>
  
  <p>(The rails server keeps running fine)</p>
  
  <p>How can I get rid of this error?</p>
