I realise that this is an old issue by now; however, I have looked into it, and to be honest, I can't seem to re-create the behaviour you've described at all. Is this still a problem for you ? If so, please describe your environment in as much detail as possible.

Hello,
I get this error too on wheezy (debian 7.5)
rabbitmq-server 3.3.2-1 from rabbitmq repository
erlang-nox 1:15.b.1-dfsg-4+deb7u1
(get the same with erlang-nox from wheezy-backport 1:16.b.3.1-dfsg-3~bpo70+1)

collectd config is /etc/collectd/conf.d/rabbitmq.conf :

# Configure the rabbitmq_info-collectd-plugin
<LoadPlugin python>
  Globals true
</LoadPlugin>

<Plugin python>
  ModulePath "/usr/lib/collectd/"
  Import "rabbitmq_info"

  <Module rabbitmq_info>
    Vhost demo
    Verbose true
  </Module>
</Plugin>

to get the error in log I just added line 59

        logger('verb',line)

I got the error as well on a centos6.5 environment.

In the end, i replaced rabbitmqctl with http api to collect statistics and it worked. I can send a pull request if needed.

@jerryz1982 I'd be interested in seeing what modifications you've made, certainly!
