Bug#906154: remmina: ssh tunnelling does not work any more

[jfp <jfp@clearfield.com>]

Package: remmina
Version: 1.2.31.2+dfsg-2
Severity: important
Tags: upstream

Dear Maintainer,

Looks like ssh tunnelling has stopped working.

When connecting  I get one of two things:
- Gets stuck on "connectiong to localhost through SSH tunnel" dialog.
or
- Failed to startup SSH session: No route to host.
[SSH] socket_callback_connected: Socket connection callback: 2 (113)
[SSH] socket_callback_connected: No route to host

I have a number of remote hosts I connect too, they all are failing.

A connection setup is as follows:
server: localhost
ssh tunnel
no loopback address
custom: SERVERNAME:PORT
username: USER
SSH Agent
