Another post suggested looking at $SSH_AUTH_SOCK which is "/tmp/keyring-bp0Sgd/ssh" so indeed it seems to be a keyring problem.
I have gnome-keyring package version 2.92.92.is.2.31.91-0ubuntu4.1
The problem occurred just after re-creating my dsa key pair (I had inadvertently overwritten the old private key). After copying the private key into the host machines 'authorized_keys" file, ssh failed with:
Agent admitted failure to sign using the key.
Permission denied (publickey).
no request for the key's password was made.
running "ssh-add" re-requested the password for the key and subsequently ssh worked.
Also on x86-64 with maverick.
