title: TYPO3 6.0.4 default controller for extension not found
body: <p>I created my third extension with the extension builder but this one won't install itself properly. I get the error:</p>
  
  <blockquote>
    <p>The default controller for extension "NtImpressions" and plugin
    "Gallery" can not be determined. Please check for
    TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin() in your
    ext_localconf.php.</p>
  </blockquote>
  
  <p>I did not modify anything in the extension files. The Plugin is completly generated by the extension builder. This is the ext_localconf.php</p>
  
  <pre><code>&lt;?php
