Thanks for the report.  It was very helpful.  It generates an error
because a read-only text remains in the " *code-conversion-work*"
buffer, and it prevents us from erasing the buffer in the next call of
`run_pre_post_conversion_on_str' (in coding.c) .

For example, the first evaluation of

(encode-coding-string (propertize (string (make-char 'latin-iso8859-1 33))
                                  'read-only t) 'utf-8)

succeeds in producing "\302\241", but the second evaluation of the
same expression results in the "Text is read-only" error.

Since displaying menus or title bars now involves code conversions
from emacs-mule to utf-8 in some platforms, this error may occur on
menu activation or C-x 5 2.
