everyone has seen the lines attached to this bug report. 

please add a note to that warning how i can list all fingerprints "FROM" and "ON" the remote side so that i could see what is going on. say i have another ssh session still running so i would not have to accept the new host key first.

the line could look like this:
******************* <please add this to the warning> *******************
You can verify your fingerprint on the remote side with:
ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key
(in case your keys are stored somewhere else, adapt the path) 

If the fingerprint from the remote side and the one your client states to be new match there is no 'man in the middle attack' going on and you can safely accept the new fingerprint on the client side with 'yes'.

@       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
The RSA host key for [domain]:port has changed,
and the key for the according IP address [ip.ip.ip.ip]:port
is unknown. This could either mean that
DNS SPOOFING is happening or the IP address for the host
and its host key have changed at the same time.

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
