Comment:
I'm not the original submitter. But I see this error on revision 12799 if
I run the development server with a port definition and access the server
via hostname instead of localhost. I'm trying to port my existing 1.1 app
to 1.2 beta.
If I do:
./manage.py runserver
And attempt to access {{{http://localhost:8000/admin}}} (or my app); all
is well.
If I try:
./manage.py runserver 0.0.0.0:8000
And attempt to access {{{http://<hostname>:8000/admin}}} (mind the access
via hostname; if I access localhost it works fine); I get this stack:
{{{
