Gnu Emacs Bug: rgrep, “find: invalid predicate `-nam'”

this seems to be a bug. Steps to reproduce:

    Start GNU Emacs with -Q.
    call “rgrep”. Search for anything.
    You get the following result:

-*- mode: grep; default-directory: "c:/Users/h3/web/xahlee_org/emacs/"
-*-

Seems quite a odd error. It appears that there's a typo somewhere that
contains -nam instead of -name, but i wasn't able to find it anywhere
so far. Note that this error occurs when starting emacs with -Q, so it
rules out personal init files.
