Comment 8 for bug 659590

Verification:

I installed bzr 2.2.4-0ubuntu1 into a maverick chroot and tried Max's reproduction instructions. It fails to ask for a password:

Uploading to ppa (via sftp to ppa.launchpad.net):
  bzr_2.2.4-0ubuntu1.dsc: No handlers could be found for logger "bzr"

<bound method SilentUIFactory.get_password of <bzrlib.ui.SilentUIFactory object at 0x14564d0>>

This is probably fixed upstream, has to do with how dput is calling bzr, and is not a regression. I installed openssh-client, which is probably what people want to use rather than paramiko, and ran an ssh-agent. The upload succeeded.

verified ok.
