[rabbitmq-discuss] Error when accessing management plugin

[Simon MacMullen]

That is definitely very odd.

The only explanation I can think of is that there is somehow another 
copy of Mochiweb (of a different version) in your Erlang code path. We 
have sometimes seen this happen when using buggy RPM or deb packages for 
Erlang programs which are not RabbitMQ; sometimes these packages make 
the mistake of installing into the Erlang OTP directory and thus being 
forcibly visible to every running Erlang application.

Does that sound like something that could be happening?

Cheers, Simon
