title: Rails Logger appears to be duplicating log lines
body: <p>I am experiencing something curious with the rails logger.</p>
  
  <p>When I insert a Rails.logger.info("Some text") in the code, usually to trace flow, I am getting two lines of "Some text" output in the console. </p>
  
  <p>This ordinarily isn't much of a problem, but when I dump the contents of larger objects, the output can get cumbersome to wade through.</p>
  
  <p>This never seemed to happen before I upgraded to Rails 4, or at least, I don't recall it happening.</p>
  
  <p>Does anyone know what is happening here, and if there is a way to stop duplicating log output?</p>
