Subject: Issue in SSL/TLS connection setup
To: bug-gnutls at gnu.org


I am facing SSL/TLS connection setup issue with python-twisted (12.0.0) and
python-gnutls(1.1.9). Version of Ubuntu (unstable), I am using is: 12.10
During the SSL/TLS connection setup, there is ClientHello request from the
client and for this request there is no response from the server where
Twisted and GnuTLS are running.
I see only TCP FIN and RST sent by the server end for the ClientHello
request.

When I checked the syslog, I see below messages.

 Traceback (most recent call last):
:   File "/usr/lib/python2.7/dist-
packages/twisted/python/log.py", line 84, in callWithLogger
:     return callWithContext({"system": lp}, func, *args, **kw)

: TypeError: loseConnection() takes exactly 1 argument (2 given)

Anyone else has faced this issue, earlier? Is this a bug in GnuTLS package?
I am not having any clue like what went wrong. Have I missed anything which
is required?
Please help me to come out of this issue.
