[Twisted-Python] xmlrpc ExpatError

[Justin Johnson]

I changed printError to...

def printError(error):
	print error
	print error.getErrorMessage()
	error.printDetailedTraceback()
	reactor.stop()

and got the following...

[Failure instance: Traceback: twisted.internet.error.ConnectionLost,
]

*--- Failure #4 ---
--- <exception caught here> ---
*--- End of Failure #4 ---

Not sure if this helps any.
