Channel API does not work in Eucalyptus

[nlake44]

Receiving works (connection to ejabberd/nginx is fine) but sending gives the following exception:
File "/root/appscale/AppServer/google/appengine/api/xmpp/xmpp_service_real.py", line 240, in _Dynamic_SendChannelMessage
client.auth(my_jid.getNode(), self.uasecret, resource=my_jid.getResource())
File "/usr/share/pyshared/xmpp/client.py", line 214, in auth
AttributeError: Client instance has no attribute 'Dispatcher'

Tested and works fine in a Xen deployment.
