title: Eclipse Kepler - PHP Code completion not working
body: <p>Today i've downloaded Eclipse Kepler and i've noticed that PHP code completion is not working anymore.
  when i type the first letters of a standard php function then press CTRL+Space, it gives me an empty list ("No Default Proposal").
  This used to work with the older version (i was using Juno) and i've made no modification.</p>
  
  <p>I've already tried removing the PHP nature and adding it again (through Right Click => Configure => Add PHP Support), but it didn't help.</p>
  
  <p>In both versions the only plugin i have installed is Aptana Studio 3.5.0 (nightly build) but i'm using Eclipse's editor for PHP, not Aptana's, nor i'm using Aptana's PHP nature, but Eclipse's</p>
