Comment 4 for bug 1420164

Just to be clear, since I hit this also, if you apply the patch above on oslo.messaging 1.6.0 and set rabbit_use_ssl=True, you shouldn't set kombu_ssl_version unless you're setting the other kombu config options for like keyfile, certfile, and cafile. I still had kombu_ssl_version set and things were still broken even with the patch until I commented out kombu_ssl_version in my conf file.
