Comment 13 for bug 1252484

Lennart, see my comment #11. This fix/SRU is for the root cause when making a backup, preventing the data loss in the first place.

But if you are trying to restore a backup affected by the bug (as you are), the traceback you see when restoring is worked-around by a separate fix in duplicity trunk. You still will not be able to correctly restore the file missing its 65k chunk, but duplicity trunk does prevent the restore from bailing out.
