I'm sorry for insufficient information.  It was caused by the
following form which didn't specify the parent group.

(defgroup smime nil
  "S/MIME configuration.")

Yesterday, I changed my mind and added the ``:group 'something''
argument to every defgroup, defface and defcustom forms in which
it hasn't been specified in Gnus (the changes will be propagated
into the Emacs trunk after a while).  At that time, I felt like
to add some first-level groups (e.g., cryptograph, security, etc.)
is necessary.  However, I'm not positive to propose adding of
them since Gnus v5.11 supports not only Emacs CVS but also Emacs
20 and 21.

By the way, I noticed the new bytecomp doesn't warn to the
defcustom form in which the parent group is not specified.  For
example:

(let ((file (expand-file-name
	     (concat (make-temp-name "testing") ".el")
	     temporary-file-directory)))
  (with-temp-file file
    (insert "\
\(defgroup foo nil \"doc\")
\(defcustom bar nil \"doc\")
"))
  (byte-compile-file file)
  (delete-file file)
  (delete-file (concat file "c")))
