I saw it last weekend too. I thought that it was an improbable edge condition,
so I did not mention it on squeak-dev until I could explain the bug.

It is not a corrupted mcz. In my case, the failure occurred while trying to
write a new mcz.

We should move this to squeak-dev and figure out what is going on.
