Ah, ClearCase? Then yeah, man, do whatever it takes to get you through
the day...

Excellent!

Not so excellent :-(

Are you on a 64-bit or 32-bit system?

What version of Pyrex? I see some discussion of such errors on the

it might require a 32-bit system to trigger anyway, and I don't have
any handy :-/).

KeyError? PIL? WTF... hopefully this is just a bug in the traceback routines...
