OK but I still don't think that I have even zeroed in on the bug. Even
the code I provided is pretty large and complex for a snippet meant to
identify the problem.

I managed to move everything into one test file and switched to the
SimpleXMLRPCSer ver module but to no avail. The new code is at
ftp://ftp.druid.net/pub/distrib/test_2.5

It seems be this issue:

http://bugs.python.org/issue1739842

Your handler in the server thread correctly catches the RuntimeExceptio n
and converts into a Fault object which it returns. Unfortunately,
xmlrpclib then throws an exception instead of marshalling the Fault
object. Your server catches the exception and turns it into a 500
HTTP server error. The client thread then throws a ProtocolError,
which is uncaught.

So exceptions are working fine in your test case, the problem is that
xmlrpclib.dumps () can't marshall xmlrpclib.Fault objects in 2.5.
