I don't think it's expected, but obviously we never reproduced it in
the lab. Given that dumpling is EOL and the huge number of changes in
all this code since then, I don't think you should expect anybody to
figure out why it broke, though. :/

Yeah, probably the backfill went through a different path that didn't
fail but copied the bad data over. You could try using the patches on
that ticket to get things up and running again...
