title: is_dir failure?
body: <p>So, from a script running in <code>/home/a-spdb/www/sofa</code>:</p>
  
  <ul>
  <li><code>is_dir("/home/a-spdb/www/sofa/uploads")</code> //returns true</li>
  <li><code>is_dir("/home/a-spdb/www/sofa/uploads/talent")</code> //returns false</li>
  </ul>
  
  <p>sshing into the server, the 'talent' folder clearly exists:</p>
  
  <pre><code>bash-3.00$ pwd
  /home/a-spdb/www/sofa/uploads
  bash-3.00$ ls -l
  total 0
  drwxrwsr-x+  2 myusername  someusergroup      96 Nov 15 00:50 talent
  </code></pre>
  
  <p>I've tried deleting the talent folder and recreating it (just <code>mkdir talent</code>), but I still can't get is_dir to accept that it is a directory.  Any idea why?</p>
