Just been updating to Django 1.3.1 and come across an odd error. I'm
getting the following error from some code which works with version
1.2.7.
FieldError: Cannot resolve keyword 'email_config_set' into field.
Choices are: id, name, site, type
The odd thing being email_config_set is a related name for a
ManyToMany field. I'm not sure why django is trying to resolve it into
a field.
To make it even more odd, this error occurs when DEBUG = TRUE and not
when DEBUG = FALSE when testing with runserver.
I've been trying to solve this for days now with much googling/pdb/
logging, but since the exception originates deep inside django I'm not
familiar enough to find what is going wrong:

Any ideas/solutions/pointers/tips would be most welcome.
