Hi

The FileUploadParser code (line 181) in rest_framework.parsers.py seems to work differently as it should be.

The line does not work in my Python 2.7.8 (OSX El Capitan):
if file_obj:

I modified and works like this:
if file_obj is not None:

Could someone confirm this buggy behavior under other situations?

Thanks.

Regards,

Yu
