If I call a zope object using a XMLRPC client, and it raises an exception, I get the name and value of the exception but no stack trace, even when Zope is running in debug mode.

An example of what is returned is below

>>> s = xmlrpclib.Server("http://localhost:8080/temp_folder")
>>> print s.dud()
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "D:\Python22\lib\xmlrpclib.py", line 820, in __call__
    return self.__send(self.__name, args)
  File "D:\Python22\lib\xmlrpclib.py", line 974, in __request
    verbose=self.__verbose
  File "D:\Python22\lib\xmlrpclib.py", line 852, in request
    return self.parse_response(h.getfile())
  File "D:\Python22\lib\xmlrpclib.py", line 895, in parse_response
    return u.close()
  File "D:\Python22\lib\xmlrpclib.py", line 570, in close
    raise apply(Fault, (), self._stack[0])

I'd say the problem lies in ZPublisher\xmlrpc.py. This should really check if Zope is in debug more and return the stack trace.
