Actually, scratch all that.  I think we should simply always pass NULL
as the first argument of LookupAccountSid.  If you compiled Emacs by
yourself, can you try such a modification there, and see if that
helps?  I'm interested to know not only whether the crashes go away
when you use NULL, but also whether the file owner and group
information is reported correctly.

Thanks.
