[issue2449] Improved serialization error logging in xmlrpclib

[Christopher Blunck]

New submission from Christopher Blunck <blunck2 at users.sourceforge.net>:

When xmlrpclib fails to serialize objects into XML a generic "failed to
serialize output" error is returned to the client and no log messages
are produced to give insight into the true cause of the problem.  In
real-world scenarios where lots of data moves along the wire it can be
difficult to determine the cause of the serialization problem.

I propose the attached patch as an initial cut at improving xmlrpclib
under circumstances where serialization fails.
