Yes, that's about right. To quote from the SSL page at

"Note there are major bugs SSL in Erlang release R13B04 which renders
using SSL with cerificates broken. As of this writing, if you're wishing
to use SSL with certificates with RabbitMQ, we recommend R13B03 as the
least buggy implementation of SSL in Erlang"

I reported several bugs about the SSL module to the Erlang developers
and there should be fixes in the R14A which got released today. However,
that is an alpha release so you may not wish to use it - I've not had a
chance to investigate it yet.

I had the most success with R13B03 wrt SSL.
