The solution is to isolate your PEMs and add them back one by one, not as a bundle. At the lowest leaf, then the parent, then the parent, etc and test each time.

See https://github.com/iojs/io.js/issues/712

I'm thinking this must be a bug in the internals of node.js / io.js where duplicate certs aren't checked the very first time they're used.

What's odd is that adding a cert to the chain for a specific https server instance can cause an unrelated https request (which should be using the default chain, not anything to do with the https server).
