title: Django AUTH_PROFILE_MODULE imports improperly
body: <p>I've got two Django apps, one (running 1.4) with the following settings:</p>
  
  <pre><code>INSTALLED_APPS = ('appname.account',)
  AUTH_PROFILE_MODULE = 'appname.account.UserProfile'
  </code></pre>
  
  <p>This works just fine. However, I have another app, that I'm porting to 1.4, which I have set the same (well, similar, they have different <code>appname</code>s) but which won't work due to a caught <code>ValueError</code> in the auth contrib package. I'm not sure where to begin looking for where to change this properly, any suggestions?</p>
