13493	ImportError when trying to use models from standalone script.	eric@…	nobody	"This is a regression between 1.2-beta-1 and 1.2-rc-1

I have a maintenance script that accesses the database via the same django models I'm using for the website.  When I upgraded from 1.2-beta-1 to 1.2-rc-1, this script started failing with the following traceback unless the PWD is the django project directory:
