Ok, a bit further.

I tried restoring a backup and re-running the conversion script. Then it
works.

The only reason I can see for this failure is that the rsync happened
just as the files were committed, and for that reason we got a partial
commit (since cvs doesn't to atomic operations). Then when we got the
rest of the modifications, the migration script had already flagged that
one was imported.

We can work off tihs that came off the backup, but that invalides the
last couple of commits, which will AFAIK break everybody who has cloned
the repository?

Does anybody know of a better way to fix it, without this happening?
