It happened twice on the same insert statement, while the rest were fine
so it is reproducable.  I will try doing a little debugging on this myself
and see if I can figure out what is going on.  A good chance to get my hands
wet on the code.  I can also provide a login account on my system for debugging
if I can't figure it out myself.
