title: ipython qtconsole on Windows printing error with no apparent side-effects
body: <p>When I launch ipython qtconsole on Windows (by punching <code>ipython qtconsole</code> into a CMD window), the following error gets printed quite frequently to CMD:</p>
  
  <pre><code>QTextCursor::setPosition: Position '4022' out of range
  </code></pre>
  
  <p>Everything in the ipython qtconsole is working to the best of my knowledge. So I'm curious, what does this error mean, and is it indicative of any underlying problems?</p>
