 I'm trying to use Pidgin at work where I have only couple of ports open. I
 have created a tunnel on port 443 for XMPP and everything works correctly
 when using Pandion or PSI but Pidgin has some problems unfortunately.

 I have created a new XMPP account, specified my own connect port, connect
 server and checked "Force old SSL". But with these options set-up I get:

 {{{

 }}}

 As you can see form the script above, Pidgin connects to the server, talks
 to it and then fails to proceed with tls encryption. It just hangs there
 for eternity. I'm not sure if tls should even be used when using SSL but
 you're the experts so I'll leave it up to you :)

 You're doing a great job, guys - there's really no superior alternative
 for Pidgin. Thanks.
