Thanks for the reply; I'll pursue it.
I'd like to dig a bit deeper into the reason for the missing traceback,
though. I had a similar "exceptions must be classes" message a while
back, and fixed it by changing Failure.raiseException in failure.py to
raise self.__class__ rather than self.type. That at least caused the
original reason for the exception to be shown.
Also, that change is still in place in the frozen exe (assuming py2exe
worked correctly), so something else is going on here.
