Thanks Daniel. Responses inline.

Yes it does.

Here's the context in the rev file:
id: y-31.0-32.r192/673830
type: file
pred: y-31.0.r31/264323
count: 1
text: 162 670867 6111 52486 5117fb0964ca1a78dd97447d23452e73
609f4745460d6e14860daff0803ee7024c54898c 191-5r/_m
cpath: [redacted]
copyroot: 32 [redacted]

Looking at the other nearby entries, they have "text: 192 [...]"
instead of "text: 162 [...]". Is that likely to be the problem?

Yes it does.

I'll find out if I can release the broken revisions in their entirety.

The corrupted revision doesn't actually contain anything particularly
important (almost all the modified files in it have since been replaced
by newer versions anyway). Can I fix the repository by dumping every
revision except 192, and then reloading the good revisions into a new
repo? Or will cause problems for the revisions after 192 since one of
the revisions no longer exists?
