15969	upgraded 1.1 -> 1.3. Now NULL in ContentType.name causes error in admin	Scott Chapman <scott@…>	nobody	"We are upgrading 1.1 to 1.3.
Oracle back end.
There are NULLS in DJANGO_CONTENT_TYPE.Name and DJANGO_CONTENT_TYPE.Model.
When I go to the Admin interface and try to change the user, an error comes up:
{{{

TemplateSyntaxError at /admin/auth/user/82/

Request Method: 	GET

Django Version: 	1.3
Exception Type: 	TemplateSyntaxError

The new version of Django has None for the value in the ContenetType.Name.  In version 1.1, it was an empty string, which would Unicode() correctly.
