After upgrading to Duplicity 0.6.19 I'm still getting the same error as below:
ReadError: missing or bad subsequent header  

Is it possible my backup is corrupt or something? I also downgraded back to Python 2.6 and the stable Debian Python packages, to no avail.

claims that this is probably fixed in 0.6.16 .. in any case please use the latest stable 0.6.19 and see if the error persists
Thanks! I didn't know what to search for to research this error further.

0.6.18 appears to be the latest version available in Debian right now, and I'm getting a different error message there, search "ReadError: missing or bad subsequent header" in Launchpad doesn't turn up anything... Any ideas, before I look for a 0.6.19 package or aim to compile my own?

Hello,

Running the following command is now producing this error message consistently... Any ideas what is causing this and what I can do to fix this? I'm using version 0.6.15.

duplicity --full-if-older-than 3M --tempdir ${TEMPDIR} --archive-dir ${ARCHIVEDIR} --gpg-options "--compress-algo=bzip2 --bzip2-compress-level=9" --asynchronous-upload --encrypt-key=${GPG_KEY} --sign-key=${GPG_KEY} --s3-use-rrs --s3-use-new-style ${SOURCE} ${DEST}

these variables, of course, have values.
