Exception raised when publishing from a pubsub object · Issue #151 · redis/redis-py · GitHub

pip freeze | grep redis

redis==2.4.5

This code works correctly:

import redis
r = redis.Redis(password='yomama')
r.publish('foo','bar')

This code fails, although the message is correctly published before the code raises an exception:

import redis
r = redis.Redis(password='yomama')
ps = r.pubsub()
ps.publish('foo','bar')

Traceback (most recent call last):
File "./test2", line 6, in
ps.publish('foo','bar')
File "/Users/nfarring/.virtualenvs/mordia/lib/python2.7/site-packages/redis/client.py", line 1136, in publish

Here is the same output using ipython:
