Pidgin / libpurple can't interact with to some XMPP/Jabber servers

Project:Trisquel

Status:active
Description

According to Dausacker and Alexandre Oliva (lxo), this affects at least Pidgin 2.12.0 (libpurple 2.12.0).

They also note that installing the “NSS preferences” plugin and in its configuration, activating “TLS_AES_256_GCM_SHA384” solves the issue.

Perhaps it's better to include that by default, update Pidgin or replace this with Gajim (preferably the latest one)?

Optionally, make a new ISO with these changes, since the tested version is the one provided inside these media.
