Patchwork breaks on Fedora 17

[Ralf Baechle]

An patchwork setup dies like this after upgrading the OS to Fedora 17:

mod_python (pid=18233, interpreter='patchwork.dead-in-the-water.org', phase='PythonHandler', handler='django.core.handlers.modpython'): Application error

  File "/usr/lib/python2.7/site-packages/django/template/loader.py", line 101, in find_template_loader\n    raise ImproperlyConfigured('Error importing template source loader %s: "%s"' % (loader, e))
ImproperlyConfigured: Error importing template source loader django.template.loaders.filesystem.load_template_source: "'module' object has no attribute 'load_template_source'"

I was able to figure out that the following seems to be needed:

diff --git a/apps/settings.py b/apps/settings.py
index 7523099..06fa64f 100644
--- a/apps/settings.py
+++ b/apps/settings.py
@@ -49,8 +49,8 @@ SECRET_KEY = '000000000000000000000000000000000000000000000000
 
 # List of callables that know how to import templates from various sources.
 TEMPLATE_LOADERS = (
-    'django.template.loaders.filesystem.load_template_source',
-    'django.template.loaders.app_directories.load_template_source',
+     'django.template.loaders.filesystem.Loader',
+     'django.template.loaders.app_directories.Loader',
 #     'django.template.loaders.eggs.load_template_source',
 )
 
But that leads to the following errors:

mod_python (pid=20390, interpreter='patchwork.dead-in-the-water.org', phase='PythonHandler', handler='django.core.handlers.modpython'): Application error

  File "/usr/lib/python2.7/site-packages/django/template/loader.py", line 138, in find_template\n    raise TemplateDoesNotExist(name)
TemplateDoesNotExist: 500.html

And of course adding a 500.html template only makes the error look "prettier" to the use but doesn't fix anything.

Do I have to dig up an older Django for Patchwork?  Any help you could give would be appreciated,

Thanks,
