Hmm I have no idea about this. It seems rdiff-backup is writing
corrupt mirror_metadata files even when the session succeeds.
(Earlier I thought they might have gotten corrupted in some crash
somehow, but it seems to be an unrelated problem.)
Offhand the only thing I can think of is a bug in python's gzip
library. Can you try making a very simple rdiff-backup repository on
any relevant computers? Try something like:
mkdir input
cat /dev/null > input/file
rdiff-backup input output
touch input/file
rdiff-backup input output
If that works, try a slightly bigger volume, and see if you notice a
pattern. If that doesn't work, I could write a very simple gzip
python test, and we would know it's not rdiff-backup's problem.

The new hash related regress code is forgetting to delete a file,
This patch should fix that, but won't fix the main problem:
