[Tiago R Magalhaes]

Hi Stephen

thanks for the  email and sorry about not having followed the correct 
instructiong to report this

(M-x emacs-version)
XEmacs 21.4 (patch15) "Security Trough Obscurity" [Lucid} 
(powerpc-apple-darwin7.4.0) of Fri Jul 16 2004

"M-x set-variable RET debug-on-error RET t RET" and then the backtrace buffer:
Signaling: (void-variable enable-multibyte-characters)
   (if enable-multibyte-characters (if (not ...) 
(fill-find-break-point after-prefix)))
   (save-excursion (beginning-of-line) (setq after-prefix (point)) 
(and fill-prefix (looking-at ...) (setq after-prefix ...)) 
(move-to-column (1+ fc)) (while (or first ... ...) (setq first nil) 
(re-search-backward "[	]\\|\\c|.\\|.\\c|\\|^") (if ... ... ...)) (if 
enable-multibyte-characters (if ... ...)) (skip-chars-backward "
