Sorry, it's me again;-)

I had 4.77 running with gnutls but tried 4.80 with openssl 0.9.8x until
today....

I've built gnutls 2.12.19 from source. I build exim as before. If I try to
connect with thunderbird from Fedora 16 it fails to connect and exim logs:
...(gnutls_handshake): A TLS packet with unexpected length was received.

Searching in older Logs my Thunderbird connected with
X=TLS1.0:DHE_RSA_AES_256_CBC_SHA1:32
to 4.77 with gnutls.

The server uses a self-signed certificate.


Same for gnutls-cli or openssl s_client. Both fail to negotiate a TLS
session using STARTTLS.

gnutls-cli (2.12.14-fc16) fails with
*** Starting TLS handshake
*** Fatal error: A TLS packet with unexpected length was received.
*** Handshake has failed

Connecting with openssl s_client shows an extensive amount of
25626 LOG: MAIN PANIC DIE
25626 string_format: unsupported type in "%z" in "tls_do_write(%p, %zu)
25626 "
in exim debug output.

gnutls-cli -v 255 shows:
starttls
220 TLS go ahead
*** Starting TLS handshake

Am I doing something terrible wrong?
