I don't know whether it will help, but it seems that it isn't the
top-level urls.py that the error is complaining about but the one in
your persons app. Presumably the top-level urlconf includes that?
As to why applying a decorator should trigger the problem, I am a bit
stumped.

I'm no expert.
"ex" == "has-been"; "spurt" == "drip under pressure"
