Comment 6 for bug 1223436

The bug has been opened on https://bugs.launchpad.net/ubuntu/+source/telepathy-gabble/+bug/1223436

"If I upgrade to telepathy-gabble 0.18.0-1 or 0.18.1-1, I can no longer connect to a jabberd2 server. The jabberd2 c2s.log simply has:
Tue Sep 10 11:13:14 2013 [notice] [12] [xxx, port=43155] connect
Tue Sep 10 11:13:14 2013 [notice] [12] [xxx, port=43155] disconnect jid=unbound, packets: 0

If I downgrade to 0.16.6-1ubuntu1, it starts working again:
Tue Sep 10 11:14:01 2013 [notice] [13] [xxx, port=37786] connect
Tue Sep 10 11:14:01 2013 [notice] [13] [xxx, port=37786] disconnect jid=unbound, packets: 0
Tue Sep 10 11:14:01 2013 [notice] [12] SASL authentication succeeded: mechanism=DIGEST-MD5; authzid=xxx, TLS negotiated
Tue Sep 10 11:14:01 2013 [notice] [12] bound: jid=xxx/xxx

I can see this by trying to connect with empathy.

Here is the requested info. Looks like this is the problem:

Attached is the log for 0.16. What I find interesting is that 0.18 is logging twice. Eg:
gabbleauthentication-DEBUG: 10/21/2013 16:13:21.904870: gabble_server_sasl_channel_start_auth_async (server-sasl-channel.c:836): Starting authentication
gabbleauthentication-DEBUG: 10/21/2013 16:13:21.904870: gabble_server_sasl_channel_start_auth_async (server-sasl-channel.c:836): Starting authentication
gabbleauthentication-DEBUG: 10/21/2013 16:13:22.139523: gabble_server_sasl_channel_start_mechanism_with_data (server-sasl-channel.c:548): Starting X-TELEPATHY-PASSWORD authentication with 16 bytes of initial data

but 0.16 is only logging once:
gabbleauthentication-DEBUG: 10/24/2013 21:24:57.750232: gabble_server_sasl_channel_start_auth_async (server-sasl-channel.c:814): Starting authentication

Don't know if this is related or not."
