OK, I got this one "pinpointed": it appears when hardlinked files change 
metadata but _not_ content, _and_ only when using API 201.

Repeater is simple:

mkdir from
date > from/fileA
ln from/fileA from/fileB
rdiff-backup -v5 --api-version 201 backup from bak
touch from/fileA
rdiff-backup -v5 --api-version 201 backup from bak

Good news is that it doesn't make you lose any data.

I created an issue for this: 
https://github.com/rdiff-backup/rdiff-backup/issues/816
BUT I'm quite confident that the warnings are innocuous, they're 
unsettling but they actually do the right thing (proof being that 
calling rdiff-backup again, without API 201, doesn't show any change 
being required).

Let me check how to fix the warning though,
