Dear Maintainers,

Pidgin 2.10.1 (libpurple 2.10.1) was configured for Google talk
but it fails to connect with the message "Der Server benutzt keine der
unterstützten Authentifizierungsmethoden",
in english: "Server does not use any supported authentication method",
which is not true(see below).

I figured out that this occurs when the hostname in /etc/hostname
doesn't match the one in /etc/hosts. After adapting the two entries,
Pidgin connected fine.

The relevant part of the debug log:
(10:51:04) certificate: Successfully verified certificate for googlemail.com
(10:51:04) jabber: Sending (ssl) (myusername@googlemail.com):
