title: Pycharm with IdeaVim occasionally makes the keyboard unresponsive
body: <p>Every so often when using PyCharm Community Edition with IdeaVim in Ubuntu 13.10, the keyboard stops accepting input and I have to restart the IDE.  The cursor still moves when I click different text areas, but I can't type anything even after pressing escape multiple times.  The keyboard works fine outside of the IDE, so I suspect it is an issue with either my use of IdeaVim or IdeaVim itself.  </p>
  
  <p>Is there anything I can do to prevent this from happening?</p>
