title: 743: unexpected token at '... in Ruby on Rails
body: <p>I saved a file named array.json on my Dropbox folder and i access to it via Dropbox API. All works fine, but when i retrieve JSON content i cannot JSON.parse that string!!</p>
  
  <pre><code>session = DropboxSession.new(APP_KEY, APP_SECRET)
  session.set_access_token(ACCESS_TOKEN_KEY, ACCESS_TOKEN_SECRET)
  client = DropboxClient.new(session, ACCESS_TYPE)
  
  json = client.get_file(DIRECTORY + '/array.json')
  </code></pre>
  
  <p>@json = JSON.parse json
  Error:</p>
  
  <p>743: unexpected token at '{"Nome" : "Mario Rossi",
  "C.F." : "ABCDEFGHILMNOP",
  "Booking Assistance" : "MARIO",
  "Status of reservation" :  "25/11/2011"}'
  JSON string is valid!! if i copy this string and paste it (manually) as parameter in JSON.parse(), json is parsed correctly!! So i think is a encoding problem...but where i wrong?</p>
