Changes between Initial Version and Version 1 of Ticket #3914

-              initial
+              v1
 If you use this model:
+{{{
+#!python
 class Page(models.Model):
     title = models.CharField(maxlength=192)
 …
     class Admin:
         list_display = ['title','parent','visible_on_menu']
+}}}
 And try to go to the model in the admin interface, the development server just dies.  There is no error, it just goes back to a command prompt waiting.
