title: Missing interpolation argument error in Redmine
body: <p>A bit of Googling led me to believe that this error happens in Rails Version &lt; 2.3.6 . 
  So i changed my environment file to</p>
  
  <pre><code>RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION
  </code></pre>
  
  <p>Now, I have 2 questions .</p>
  
  <ol>
  <li>I continue to get the redmine error. </li>
  <li>When I do a script/server, I get this :
  Rails 2.3.5 application starting on <a href="http://0.0.0.0:3000" rel="nofollow">http://0.0.0.0:3000</a></li>
  </ol>
  
  <p>even though I've clearly instructed it to load Rails 2.3.8 ! Any ideas ? Thanks! </p>
