I am assuming that the following commit is intended to fix the bug that John
reported:

	> This fixes the runtime crash seen for seed 655329422

It would be helpful, though, if bug reports like this were answered more
directly, as opposed to requiring people to put two and two together.

Maybe we should start using the issue tracker at GitHub.  What do you guys
think about that?

Eric.
