No, this is different.  I'm currently chasing two issues; one which
is an intermittent call to strcpy with NULL, due to some path issues,
and a later failure to load a security library (which isn't a fatal
error).  The earlier crash I referred to happens much later than tese
(right now I have the security thing abort), but all of these are
sometime after what you're talking about.   Of course, it's
possible I missed out some part of the patches I put in, too.

Well, I certainly don't have enough information to rule out
the later crash there.  Anyway, thanks for looking as this;
people are not often interested in looking at such hard
problems :-|
