That is the full stack trace. I have just one piece of middleware:
import re
class LastSiteUrl(object):
def is_admin_url(self, url):
if re.search('^(http:\/\/.*){0,1}\/admin\/', url) is None: return(False)
else: return(True)
def process_request(self, request):
if self.is_admin_url(request.path) and \
not self.is_admin_url(request.META['HTTP_REFERER']):
request.session['last_site_url'] = request.META['HTTP_REFERER']
I don't see how that could be causing this. What changed in 1.5 to
break this? In 1.4 I do not get this error with the same middleware.
