title: Log messages disappear from GAE dev server when running a backend instance
body: <p>I am developing a web application on an App Engine backend using the GAE dev server. My problem is that as soon as I start serving pages from the backend, log messages stop appearing on the log console. Not all logging goes away. The start up log entries look normal.  I even see that annoying "can't open zipfile" message with tags that show that the message was logged from the backend instance. It's only logging calls executed when my pages are served by the backend instance that don't appear.</p>
  
  <p>I don't know if this is a bug or if I should be looking some other place for my logs. If I upload the app to the production server and look in the logs, the messages are present.</p>
  
  <p>Any help would be appreciated.</p>
