The two password prompts are some aspect of the problem as the first
one doesn't pause to wait for any input.

Here is the output of "ssh -vvv" from both ssh 6.4p1 and 6.6p1 talking
to the same sshd (6.5p1) and using the same ssh-keysign (6.6p1).  I
know I'm mixing things a bit, but the behavior is the same no matter
which sshd is being used.  I replaced hostname, IP address and home
directory paths.
