Dear Maintainer,
while using backupninja I noticed that backups were not completed
after the Update to Debian Jessie.
Errors from backupninja were like this:
Info: Duplicity cleanup finished successfully.
Info: Duplicity remove-older-than finished successfully.
Error: Local and Remote metadata are synchronized, no sync needed.
Error: Last full backup date: Thu Jun 25 04:00:40 2015

Fatal: Duplicity failed.
Debugging this further revealed that the problem is with the sftp
Backend in duplicity which is provided by paramiko. Debugging further
lead to these debug entries from paramiko:
