Output of pidgin -d

Description of problem:
Logging in to google talk account fails because of handshake failed. When I try to log in on rhel 8.1 (pidgin-2.13.0-5.el8) it works properly.

I run pidgin with -d and the conversation and the communication with server looks like this:

(09:39:53) jabber: Sending (pidgintest.2@gmail.com): <stream:stream to='gmail.com' xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0'>
