Package: duplicity
Version: 0.6.18-3
Severity: grave
Justification: renders package unusable
Dear Maintainer,
Since yesterday's update, backup to a SSH target is broken and leads to this
stacktrace:
ssh: Unknown exception: CTR mode needs counter parameter, not IV

*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
The upgrade of python-crypto from 2.6-4+deb7u3 to 2.6-4+deb7u4
* What exactly did you do (or not do) that was effective (or
ineffective)?
I did a downgrade of python-crypto to 2.6-4+deb7u3.
* What was the outcome of this action?
My backups are working again.
* What outcome did you expect instead?
