*Found the error:*
I installed modal_announcements module Looong ago; since I wanted to modify
it, I then copied the code to my project and adopted it as needed; it did
not give me errors.
But after installing celery it somehow picked the old modal_announcement's
urls (or views, or whatever...) from .virtualenv instead of my project and
exposed the error to me in this tricky way. Took me ages to figure out!
Morale: clear up properly!
