title: Can't log in to my Facebook App on local machine through ruby on rails site
body: <p>I have a Ruby on Rails site, and am in the process of redoing the Facebook app.</p>
  
  <p>The trouble is that when I try to login via Facebook on my local machine, the web server crashes and I get an error of 'Abort Trap 6.'</p>
  
  <p>More of that error message:</p>
  
  <pre><code>/Users/**/.rvm/gems/ruby-1.8.7-p374/gems/httpclient-2.3.4.1/lib/httpclient/session.rb:303:     
  [BUG] Segmentation fault
  ruby 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin12.4.0]
  Abort trap: 6
  </code></pre>
  
  <p>Now, after I get 'Abort Trap 6,' I can start up the web server again, but if I go to my localhost:port configuration, I wind up at an error page that looks like this:</p>
  
  <pre><code>undefined method `call' for 1025:Fixnum
  </code></pre>
  
  <p>And then it won't work — nothing at all works.</p>
  
  <p>I know the Facebook App ID/Secret is correct, so can anyone point me in the right direction? (I know I'm on an older version of ruby/rails, but I unfortunately can't update).</p>
