[Zope] External methods and images

[Wolf Logan]

one other thing: this will only let you see the "real" exception that's
causing the failure. there's still probably some problem with the external
method you're calling, but at least now you'll be able to locate it.

i think what you're seeing is the by-now-infamous ExternalMethod
exception-handling bug (tm). ExternalMethod is seeing an exception in some
part of the external method. in processing that exception, it assumes the
exception type is a string, which it almost never is. this usually causes a
second exception in the exception-handling code, which kills the function
(and produces the traceback you see).
