Can't connect AFP over SSH any more (LAN, not tunneled)

[michaelsanford]

I've always had "Allow secure connections over SSH" checked in the AFP connection dialogue.

All of a sudden, now, when I try to connect from my iMac to my iBook I get a message dialogue saying "Impossible to create a secure connection using SSH, click Continue to continue at a lowered security".

I did recently change the name of my iBook (changed the capitalization) in the Sharing pane.

I'm suspecting the SSH host key is no longer valid but that, in a typical Apple need-to-know-error-message way, it's not saying so.

How can I identify that as the problem? I can still SSH in from the shell, and can still mount iMac volumes with SSH support over AFP on my iBook. (before you ask, I already deleted the iBook's host key fingerprint from my iMac's ~/.ssh/known_hosts file, woops).
