This obviously is a SSL-related problem. I think curl uses OpenSSL the
correct way and then things like "Re-negotiation handshakes" should be done
in the underlying layer that curl never knows anything about.

Anyway, I've tried search around for the answer to this problem and while
I've noticed that others too have experienced similar problems I haven't read
any really good analyses or prescriptions.

You should however start out with trying to force SSLv3 by using the -3
option as it might not renegotiate properly otherwise (as explained by Joshua
Chamas here:
http://groups.google.com/groups?hl=sv&selm=9b521b%24gaf%241%40FreeBSD.csie.NCTU.edu.tw).

Does this work using your favourite browser/whatever? Some answers seeem to
point to problems in the server configs...
