You'll get the best support by asking the community (join the mailing list),
but if you have corruption in your backup destination, most likely the solution
for you is to start a new fresh backup free of corruption. It's not a bug, but
a feature you'd benefit from, if rdiff-backup had the ability to automatically
detect corruption, rewind to a point before the corruption, and then continue
forward with minimal effort and maximal efficiency... I just don't see that
happening...
