I found it and uploaded it here:

    http://starship.python.net/crew/mwh/new-style-exception-hacking.diff

The change to type_str was the sort of unexpected change I was talking
about.

TBH, I'm not sure it's really worth working from my patch, a more
sensible course would be to just do the work again, but paying a bit
more attention to getting a maintainable result.

Questions:

a) Is Exception to be new-style?

b) Somewhat but not entirely independently, would demanding that all
   new-style exceptions inherit from Exception be reasonable?

Cheers,
