Very good.  Did that too late for fridays backtrace, but this morning
I got more useful information.

Anything more I can do to figure out what is going on?  This was
running in safe mode, btw.  I suspect there is some race condition
somewhere, but do not know how to figure out where.

Happy hacking,
