title: pandas read_csv working only as root user
body: <p>I am reading a csv file using pandas. It works fine if I run script as root user. But when I try to run it with different user it does not read data and gives:</p>
  
  <pre><code>error :  KeyError: 'no item named 0'
  </code></pre>
  
  <p>it appears at: </p>
  
  <pre><code>dt = pd.read_csv('rt.csv', header=None).fillna('').set_index(0).to_dict()[1]
  </code></pre>
  
  <p>Btw, I am working on Ubuntu 12.02 and using anaconda, which is installed in root user and other user as well (which is giving error) 
  Please help.</p>
