reading zipfile; problem using raw buffer

[Sells, Fred]

Thanks all,  adding the 'rb' and 'wb' solved that test case.

The reason I read the file "the hard way" is that I'm testing why I
cannot unzip a buffer passed in a file upload using django.

While not actually using a file, pointing out the need for the binary
option gave me the clue I needed to upload the file

All is good and moving on to the next crisis ;)

Fred.
