As John said, the revision where it fails is 126 and not 125 which verified
okay.

As for how to restore the repository to a working state, you simply reload
revisions 0 to 126 from backup while using the live repository to dump the
following revisions and then reload those as incremental changes.
Alternatively, you simply load the backup up to where you have it and the
rest from the live repository.

It should be possible to keep on using the same WCs as before.
