  This is on a freshly installed VM. Per-command provisioning of this VM (from a fairly basic CentOS 6.6 image, provided by Rackspace) can be found here - https://gist.github.com/law/2920145fe65b3154a20d

  The S3 ACLs on the bucket are set wide open, and verified with s3cmd GETs, LSes, and PUTs using the same credentials provided to Duplicity - https://gist.github.com/law/858c55d43f8241a0719c

I am getting the same traceback on Ubuntu 15.04 with Python 2.7.9.

My last successful backup was apparently 15 days ago, about the time that I updated to 15.04.

[Kenneth Loafman (kenneth-loafman)]

This has been fixed in 0.7.02 and has been released a while back.
