OK. I will start talking with Handa-san again.

I will ask him, whether or not Mew should guard with
	(if (char-valid-p 256) 256 ?x)

Unfortunately, CVS HEAD today is broken. I cannot compile it. So, it
would take a time.

One suggestion: backtrace does not show much information if Emacs Lisp
files are byte-compiled. Removing *.elc and executing Emacs would show
much information in backtrace.
