------------------------------+--------------------
When a File object is created from a tempfile.SpooledTemporaryFile, an
exception occurs when the File.size method is called and the
tempfile.SpooledTemporaryFile isn't large enough to have been written to
disk. The exception is caused by an attempt to call os.path.exists on a
None value. The name attribute of the tempfile.SpooledTemporaryFile in
this case is None in this case because it doesn't exist on disk.
Patch in pull request at https://github.com/django/django/pull/2455
The patch just adds another condition before calling os.path.exists to
verify that the file name isn't None.
