SystemError on attempt to publish to the topic exchange in kombu

[narun4sk]

The following code:

from kombu.transport import librabbitmq
from kombu import Connection, Exchange

transport = librabbitmq
virtual_host = '/'
hostname = '127.0.0.1'
port = '5672'
userid = 'guest'
password = 'guest'

conn = Connection(virtual_host=virtual_host, hostname=hostname, port=port, userid=userid, password=password)
chan = conn.channel()

exchange = Exchange(name='ami_exch', type='topic', channel=chan, durable=True, auto_delete=True, delivery_mode='persistent')
exchange.declare(nowait=False)

msg = exchange.Message("Test MQ message.")
exchange.publish(message=msg, routing_key='ami.ctl')

Throw SystemError exception:

Any thoughts why, please?

I'm not sure, but probably an issue with librabbitmq so I suggest trying pyamqp://
