Comment:

 Hello, i have exactly the same problem;
 The problem seems to occur when the SSH server is running on a non-default
 port. For example my SSH server is running on port 11111 instead of 22.

 Steps to reproduce:
 * Delete ~/.ssh/known_hosts
 * Connect to mypc.homeip.net:11111
 * Unknown host key -> check 'always' -> allow
 * 1 line added to ~/.ssh/known_hosts
 * Disconnect
 * Connect to mypc.homeip.net:11111
 * Unknown host key -> check 'always' -> allow
 * 1 line added to ~/.ssh/known_hosts (total = 2 lines now)
 * Disconnect
 This continues forever, always adding another new line to the known_hosts.

 So my guess is the problem probably has got something to do with the
 hashing of:

 {{{ [mypc.homeip.net]:11111 ssh-rsa <hostkey> }}}

 for hosts with non default ports, versus:

 {{{ mypc.homeip.net ssh-rsa <hostkey> }}}

 for default ports.
