Comment(by gagern):

 The patch I just attached is something of a middle road. It limits MSN
 soap connections to SSL 3 or TLS 1.0. Connections using TLS 1.1 are not
 even tried, which avoids much of the machinery that would be needed for
 bug detection and fallback. On the other hand, the version limit only
 applies to MSN, therefore other protocols with proper server
 implementations won't suffer. Verbose comments in multiple suitable places
 indicate the workaround as such and suggest its reevaluation.

 As the API of libpurple changes, it might that all this will have to wait
 until 2.6.0. On the other hand, the implementation of purple_ssl_connect
 stays compatible, and instances of PurpleSslConnection should only ever be
 passed around as pointers, so a change in its size should not matter. If
 you decide to include this in 2.5.x, please change the @since comments
 accordingly.

 By the way, I've tested the patch. Got a successful TLS 1.0 connection to
 65.54.170.19. Prooves my point that a successful connection using GnuTLS
 is possible.
