title: PyCharm project files have disappeared
body: <p>I was working on a python project in <a href="https://www.jetbrains.com/pycharm/" rel="noreferrer">JetBrains PyCharm 2016.2</a> on Lubuntu and all of a sudden, all my project files have disappeared from the IDE.</p>
  
  <p>I have tried the following with no success:</p>
  
  <ol>
  <li><p>Exit PyCharm, navigate to project root, delete the .idea file, open PyCharm, create a new project from the current projects source.
  <strong><em>Result: seems to load fine, but cannot see any project files in either "Project" view or individually load and view any files.</em></strong></p></li>
  <li><p>Fresh download and run of PyCharm, repeating the above step.
  <strong><em>Result: Same as option 1.</em></strong></p></li>
  <li><p>Using <code>File &gt; Open</code> to open the project again.
  <strong><em>Result: Same as option 1.</em></strong></p></li>
  </ol>
  
  <p>I can do a search by file or class name within PyCharm and the search does find the files. But on selecting one to load from the search results, the search dialogue just closes and the file is not loaded.</p>
  
  <p>Also to clarify, I still have the files on disk in the project root physically. But PyCharm is not displaying them in the IDE.</p>
