Weird Django Artifact Error

I was writing a view in Django and I accidentally tried to import from
a module 'djang.form.formsets'. Naturally this didn't work so I fixed
it, but I still continue to get an error like it's there. I've tried
removing all pyc files, removing the import line and all the
subsequently affected lines, but I still get the error. Here's the
traceback: http://dpaste.com/369991/

I'm totally stumped why it would do this and what I'm supposed to do to fix it.
