title: PyCharm - some breakpoints not working in a Django project
body: <p>I'm seeing some bizarre behaviour in PyCharm. I have a Django project where breakpoints stopped working in some files but not others. For example, all the breakpoints in my app's views.py work fine, but all the breakpoints in that same app's models.py are just ignored. </p>
  
  <p>I've tried the following but no joy:</p>
  
  <ul>
  <li>double-check the breakpoints are enabled</li>
  <li>removing/re-adding the breakpoints</li>
  <li>closed/re-opened the project</li>
  <li>quit &amp; re-launch PyCharm</li>
  <li>delete my configuration and create a new one</li>
  </ul>
  
  <p>Some details:</p>
  
  <ul>
  <li>PyCharm 2.7.3</li>
  <li>Python 2.7.2 (within virtualenv)</li>
  <li>Django 1.5.1</li>
  </ul>
  
  <p>I'm not using any special settings in my configuration. Any ideas?</p>
