title: Django model: delete() not triggered
body: <p>I have a model:</p>
  
  <pre><code>class MyModel(models.Model):
   ...
      def save(self):
          print "saving"
          ...
      def delete(self):
          print "deleting"
          ...
  </code></pre>
  
  <p>The save()-Method is triggered, but the delete() is not. I use the latest svn-Version (Django version 1.2 pre-alpha SVN-11593), and concerning the documentation at <a href="http://www.djangoproject.com/documentation/models/save_delete_hooks/" rel="noreferrer">http://www.djangoproject.com/documentation/models/save_delete_hooks/</a> this should work.
  Any ideas?</p>
