    Angry Duplicity

    Hey folks,

    running 12.04.1 LTS here (up to date), duplicity 0.6.18. I am doing a daily backup of my local system. The Full backup works fine, the first incremental too, but further incrementals crash with this error:

    (You can see the full argument list et all there).

    Code:
    Using archive dir: /home/myuser/.cache/duplicity/79738e63cd90f8ccfbe70d8f1d0322f6
    Using backup name: 79738e63cd90f8ccfbe70d8f1d0322f6

    Re: Duplicity

    I would file a bug report with the project. They may also be able to find a fix or workaround for you in the meantime.
