I'm changing the status of this bug to reassign (back to Troy). I'm unable to reproduce the problem, and I'm hoping that he can shed more light on the conditions that led to this failure. I suspect that many more steps are required.

Rick, if you wait nearly a month to look at the problem and then decide you can't reproduce it, just mark it as WORKSFORME
