Pidgin 2.5.2 failed to connect

[Stefan X]

I was happy to tryout Pdigin 2.5.2 which should fix the ticket #1435
("server handshake failes due to cipher spec mismatch"). Unfortunately
connecting to my Jabber account (ejabberd) through port 5222 (new TLS
protocol) still fails. Connecting with old SSL to port 5223 is still
possible. Here is the debug log when connection to port 5222:

My ejabberd server tells me "Accepted connection".

Any ideas what may be the cause of this problem?
