Re: [Duplicity-talk] Traceback on backup with 0.5.17

[Kenneth Loafman]

This error indicates a problem in packing the header for the tarfile.
It happens very rarely, but is normally something really odd, like an
extremely long file name, a very long user name or group name, something
like that.  If you would run this again with the -v9 option, maybe I can
spot where the problem is and we can find a workaround.

...Thanks,
