title: Rubymine can't recognize ruby file
body: <p>The file attendance_statistics_controller.rb can't be recognized as a ruby file. All other files can and when i change the name to anything else this one can aswell. It has nothing to do with the length of the filename.</p>

  <p>The image on top shows how the ruby file is recognized as a textfile. Changing the name does the trick as shown on the one on the bottom. </p>

  <p>Is it a bug in the application or is there something to do about it?</p>
