Comment 1 for bug 1367675

I can confirm this bug, running 0.7.02-2 on debian jessie, though strangely I could connect successfully to the Yahoo IMAP backend and upload files for some time before I got the error. I then couldn't connect anymore.

Anyways, I someone else is wondering the "line 215" referred to is the in duplicity's imapbackend.py file, in my case located in /usr/lib/python2.7/dist-packages/duplicity/backends/ (find it by typing "locate imapbackend.py" in the terminal).
