title: Multiple errors with Package Control in Sublime Text 3
body: <p>I have installed Sublime Text 3 (unregistered, version: 3103 linux x64).</p>
  
  <p>Now I want to install Package Control. </p>
  
  <p>I tried to do this by paste the  <a href="https://packagecontrol.io/installation#st3" rel="nofollow noreferrer">code</a> into the console.</p>
  
  <p>But I had the follow error:</p>
  
  <pre><code>TypeError: unsupported operand type(s) for +=: 'NoneType' and 'str'
  </code></pre>
  
  <p>Next, I tried to manually install Package Control, but when I click the Preferences > Browse Packages… menu. But I saw the next:</p>

  <p>What I should do to fix it?</p>
  
  <p>p.s. there is no 'package_control' in the 'ignored_packages' setting</p>
