Comment 15 for bug 1266763

Ken, I will check where this can be an issue and will adapt.

I also added lock release at the bottom of the duplicity.py after the following :

 __name__ == "__main__":
    try:
        with_tempdir(main)

    # Don't move this lower. In order to get an exit
    # status out of the system, you have to call the
    # sys.exit() function. Python handles this by
    # raising the SystemExit exception. Cleanup code
    # goes here, if needed.
    except SystemExit, e:
        # No traceback, just get out

My take is that it needs to be done for every except section.

I'll do my best to propose a MP soon.

Thanks for your insight
