I wasn't able to reproduce the problem exactly as you reported, but at
least there were an error that caused the nonces to mismatch, and I
suspect both errors were caused by the same bug.
The patch below should fix it, this has been installed in CVS, and I'm
now going to work on fixing the TLS stuff to match the latest draft,
and then release 0.0.30. Either apply the patch below and test it
again and tell me if it works or not, or wait for 0.0.30.
Thanks for the report!
