Comment:
I found the bug. It's the lazy object implementation of the default
storage. It doesn't work in python 2 using multiprocessing.
This little snippet allows to produce the error.
{{{
def has_location(storage):
return hasattr(storage, 'location')
def test_multiprocessing_lazy_objects(image_upload_file):
SimpleModel.objects.create(image=image_upload_file)
obj = SimpleModel.objects.last()
storage = obj.image.storage
p = Pool(2)
assert all(p.map(has_location, [default_storage, storage]))
}}}
