Don't mind at all.  I'm now working with a zip file with some dummy
data I downloaded from the web service.  You'll notice it's a smaller
archive than the one I was working with when I ran zip_susser.py, but
it has the same problem (whatever the problem is).  It's the one I
uploaded to http://webcomm.webfactional.com/htdocs/data.zip

Here's what I get when I run zip_susser_v2.py...
