Bug Description
This bug could be invalid as I don't know enough about the duplicity internals, but it's worth putting out there in-case it makes sense.
As I understand it, duplicity uses rdiff differences as opposed to rsync which offers advantages of history but a disadvantage in redundancy.
If a single byte in the chain of your rdiffs goes arwy then, as far as I understand from reading a tutorial long ago on the merits of rsync snapshot backups vs rdiff, your file is corrupt.
You could add redundancy for this by using the par2cmdline package. Although often used for dubious purposes, much like bittorrent, it could also be used for good, having a small amount of extra space maybe 5% redundancy provided by par2 should solve the issue.
