As I'm also affected, I'd be happy to contribute a patch for the solution with the hash. However, I'm not totally sure if I understand everything correctly on the mailing list.
 - I assume that it suffices to store a hash of the manifest file locally. Am I right?
 - Is adding a LOCAL file with the hash in the cache directory really invasive, i.e., would it involve changes in other parts of the code or break backwards compatibility? If the local file is not there, we could easily fall back to the current implementation.
 - If adding a local file is invasive, maybe adding the hash value to the local filename could be a neat trick (might be simpler than a hash neutral line).

btw, the link above is broken. This is the discussion on the list: https://lists.nongnu.org/archive/html/duplicity-talk/2010-12/msg00004.html
