+"""Add permissions for proxy model.
+
+This is needed because of the bug https://code.djangoproject.com/ticket/11154
+in Django (as of 1.6, it's not fixed).
+
+When a permission is created for a proxy model, it actually creates if for it's
+base model app_label (eg: for "article" instead of "about", for the About proxy
+model).
+
+What we need, however, is that the permission be created for the proxy model
+itself, in order to have the proper entries displayed in the admin.
