I finally had a chance to fix this problem.  The error only occurred at the edge of a 20,000 character buffer.  Anyway, I'm attaching a fix herewith (since it's small), and I will update SM when I have some better success with FTP.

Thanks for the report.  I'm interested if things are solid now (they have been for me).
