Not only that: I deleted the offending line from my ~/.ssh/known_hosts, re-accepted the key as valid (of course I have no idea), and attempted to pull, and it asked me for my Savannah password -- ie, did not go to my local ssh key. That really made me wonder -- does that mean we've switched machines altogether, and the new machines don't have our public keys? I don't know how all these things work well enough to know what's going on, but it certainly seems broken.
