title: What happen when I add a Django app to INSTALLED_APPS?
body: <p>Here is the situation.  I have a django project with two installed apps.  Both apps appear to function properly if they are installed independently of each other.</p>
  
  <p>However if I list both apps in the settings.INSTALLED_APPS the reverse() function seems to break for urls in the first app.  So this leads me to believe that a bug in the second app is causing the problem.</p>
  
  <p>If I simply remove app_2 from the settings.INSTALLED_APPS, app_1's url reverse() begins working again.  So the question becomes what "Magic" is happening when I add app_2 to the settings.INSTALLED_APPS?  Where should I be looking in app_2 for code causing this problem?</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>I have narrowed down the problem a little, but it just gets stranger.   app_2 has an admin.py file that defines a few custom admin views.  In that file is a line that calls reverse:<br>
  <code>reverse('init_script_view', args=['id_content'])</code></p>
  
  <p>As long as that line is in the admin.py file all calls to reverse() fail with a NoReverseMatch exception.  If I remove that line, everything seems to work fine.</p>
