Probably.  The preview-latex initialization file (and notice that you
are loading _two_ different preview-latex initialization files in the
above, quite suspicious) is supposed to define an autoload for
preview-report-bug.  According to the ChangeLogs, this is supposed to
happen starting with version 0.7.6 (when the appropriate autoload
cookie has been added to Debian).

So it would appear that the preview-latex.el file which is supposed to
be generated new on each distribution, has been generated once for
Debian in some older version, and never again, but rather checked in
in the original form.  Or the Debian initialization file actually is
from a time where we did not even generate autoloads automatically.
Maybe this was done to avoid enabling preview-latex without further
questions (but one could still manually disable it with
  (remove-hook 'LaTeX-mode-hook #'LaTeX-preview-setup)
) if one really did not want to use the package.

The file looks somewhat like the following currently for a CVS Emacs:

;;; preview-latex.el --- automatically extracted autoloads
;;
;;; Code:


;;;### (autoloads (preview-report-bug LaTeX-preview-setup) "preview"
;;;;;;  "preview.el" (16886 65165))
;;; Generated autoloads from preview.el

(autoload (quote LaTeX-preview-setup) "preview" "\
Hook function for embedding the preview package into AUCTeX.
This is called by `LaTeX-mode-hook' and changes AUCTeX variables
to add the preview functionality.

\(fn)" nil nil)
 (add-hook 'LaTeX-mode-hook #'LaTeX-preview-setup)

(autoload (quote preview-report-bug) "preview" "\
Report a bug in the preview-latex package.

\(fn)" t nil)

;;;***

;; Local Variables:
;; version-control: never
;; no-byte-compile: t
;; no-update-autoloads: t
;; End:
;;; preview-latex.el ends here
(add-to-list (quote load-path) "/usr/local/emacs-21/share/emacs/site-lisp/preview")
