I'm not surprized at all by this, the handshake it build so that most
cases which would transparently work by default will fail ! This is the
big failure of this protocol right now. We're trying to break compatibility
with 10 years of work towards interoperability between components that
try their best to be transparent to each other, and everything will have
to be reinvented from scratch.
