desktopcouch-service crashed with Unauthorized in request(): ('unauthorized', 'Authentication required.')

[Curtis Hovey]

Having switched from Evolution to Thunderbird, and removing the former, I assumed that desktop couch was unneeded. I started seeing errors a few days ago when I tried to use deja-dup. I attempted to fix the issue by deleting the *both* passwords owned by desktop couch, then deleting the couch ini and html files. After restarting and opening U1, I got this error. I do not see a U1 option in deja-dup.
