Are you building without openssl?  If it can't create
sha1s then that would cause null GUIDs.  Hmm.  Perhaps
this is a bogus commit.  Feel free to build without it,
it won't break anything.

It was put in to avoid the case where broken appends
were happening due to a bug in another part of the code,
but the bug has been fixed separately now.
