This is a simple screw up it looks like...if you're familiar with
python, then I'll just tell you that it's a namespace screw up.  I did
"import Cache" at the top of that module, and I should have written
that as "except Cache.CacheException, exceptionstr:" - CacheException
doesn't exist in that module.  This is a little bit odd though, since
it shouldn't be a windows only thing.

Every time you try to load a file, it checks the cache.  If it's in
the cache, it returns the necessary information, and if it's not in
the cache, then it raises a CacheException, which in this case wasn't
caught due to a simple namespacing issue.

If you want to, you can grab a fixed version at

Thanks for pointing this out - let me know about anything you find.
