can not connect to non-default port on IPv6 enabled host

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enter hostname which will resolve to IPv6
2. Change port to non-default (e.g. 443)
3. Try to connect on IPv6 capable network (host is accepting connection on this 
port via IPv6)

What is the expected output? What do you see instead?
"Host has disconnected. Close session?" (See attached screenshot for more 
details)

I expect to connect to the host.

What version of the product are you using (you can see this by using Menu
-> About in the Host List)?
1.7.1

What type of system are you trying to connect to?
SSH to a dual stacked host on non default port (fraktalgemuese.de:443)

If you are able to connect, what is the output of "echo $TERM", "uname -a",
and any other relevant information on the host?

Please provide any additional information below.
