With the following test case, I'm not able to reproduce what you're
describing.
But yes, die-ing here and not being able to gracefully recover is a
nasty bug...
Warning instead of die-ing here is not a good option, because it can
lead to inconsistent author data inside populating history. I believe
it's better to error out immediately so the user can fix their authors
file.
