If you have time, you should update to the RELENG_4 branch and confirm that the problem goes away for you. Although it was a few weeks late, I do appreciate the quality of your bug report. Had Jeffery not already worked on the problem, your report would have been a great help in finding a solution. Tell us if you find any more bugs!
