Public bug reported:
I've set up Deja-dup to backup my home directory to Ubuntu One, but the
backups are failing. I previously had the Ubuntu One Nightly PPA
configured, but due to this problem and a couple of others, I reverted
it. Unfortunately, the backups are still failing.
The error message is:
Traceback (most recent call last):
