Can’t decrypt SSL traffic

I'm trying to decode SSL traffic but I'm failing so far. I seem to have the correct private key but I can't make sense of the log file. At first I was using ECDHE and modified my application to dump the pre master secret but that failed in a very similar way.

The capture file and private key can be found here: https://www.dropbox.com/sh/4o0qr7hwfoobyrz/AACzzEk9VlrL6XpVQfztIsfma

This is not https traffic but a custom protocol that sits on top of SSL.

Any pointers would be greatly appreciated!
