[rabbitmq-discuss] JSONRPCError - Internal error: badmatch

Wed Aug 11 17:41:25 BST 2010

Cameron,

It appears that rabbitmq-jsonrpc-channel had outdated signature for
basic.consume. We've fixed that in the default branch.

Could you try again, and let us know if the new code works better?

Cheers,
  Marek
