title: Error when starting vim
body: <p>I am getting the following error on vim startup:</p>
  
  <pre><code>Error detected while processing function &lt;SNR&gt;71_OnBufferRead..&lt;SNR&gt;71_SetOmnicompleteFunc..&lt;SNR&gt;71_Pyeval: line    2: /usr/local/lib/python2.7/dist-packages/cffi/model.py:532: UserWarning: 'point_conversion_form_t' has no values explicitly defined; guessing that it is  equivalent to 'unsigned int'   % self._get_c_name())
  </code></pre>
  
  <p>Anyone know a quick fix?</p>
