[Zope] Can't get ZClient to work, zope 2.2.0

[Bill Welch]

hit http://zope.carbonecho.com/forum/sepServe to see the error
('expecting read-only buffer...')

here's the external function:

from ZPublisher import Client

def ServePHP(url='http://www.yahoo.com', username='bill', password='xyz'):
	print 'Sep Serving ' + str(url) 
	return Client.call(url, username, password) [1]
