.ssh dir is chmodded 700, 600, id_rsa 400.

I ran ssh-keygen -t rsa, imported key to launchpad and ran bzr branch lp:unity, but got error message:

Agent admitted failure to sign using the key.
Permission denied (publickey).
bzr: ERROR: Connection closed: Unexpected end of message. Please check connectivity and permissions, and report a bug if problems persist.

Are you running ssh-keygen or are you running sudo ssh-keygen? – James T Nov 28 '10 at 23:12
I'm running ssh-keygen. – Delirium tremens Nov 28 '10 at 23:17
The user is connecting to Launchpad, so neither his auth.log nor authorized_keys have anything to do with the problem. – grawity Nov 29 '10 at 15:37

You may need to load the key into the agent with ssh-add.

If you've done that, check if you're affected by one of the related Ubuntu bugs: 201786, 328127, 488296.
