Grapelli, Django, and objects_name

KeyError exception that says "objects_name" is not defined.

http://groups.google.com/group/django-grappelli/browse_thread/thread/160e85c07557d280

The issue has already been reported here:

http://code.google.com/p/django-grappelli/issues/detail?id=342

The problem appears to be that the objects_name template context variable has been changed in the latest Django dev distribution (but apparently not in Django 1.3 beta that's currently on the site). You have to copy the templates/admin/delete_selected_confirmation.html from the django-grappelli directory into your own templates/admin directory, and then change objects_name variable to object_name. This patch appears to fix the issue:
