I was able to recover the "critical" data this way (mounted a second image
and ran python,busybox and rsync to salvage the data at known locations under
the problematic directory).
Right now, I think that 2-3 sections of medatata had been overridden by data
very recently. These sections are very small, so I don't think it was a discard
issue. And I think this must have been provoked somehow by older crashes a few
weeks ago.
My disk image is still there in case someone wants to play with it.
