I try to create a new Jabber account with Empathy and Gabble is blocked with
this stack:

Continuing.

I cannot chat with other Jabber account since Gabble is blocked. Restarting
Empathy does not help because Gabble is still blocked.

According to strace+netstat, Gabble waits some bytes from the Jabber server and
this tcp connection is established.

There is maybe 2 problems here:
1/ the jabber server sends nothing and Gabble want to receive something. I
don't know if this is a bug from the server or the client.
2/ Gabble do not use non-blocking socket. If the server is bogus, using
blocking socket will prevent the user to chat with contacts on other Jabber
accounts.
