D'oh! (like Homer Simpson)

I missed the fact that in the first case you are doing sudo and in the
second you are doing it as a normal use.  It won't work that way.  Root
is its own user.  You need to either set up root as a key on the remote,
or in /root/.ssh/ add a 'config' file with the following lines.

IdentityFile /home/user/.ssh/id_rsa
IdentityFile /home/user/.ssh/id_dsa

where 'user' is your user name.

You may also use "--ssh-options="-oIdentityFile=/home/user/.ssh/id_rsa"
on the duplicity command line.
