Hi,
I got the following error when sending the bug#6009 report
containing the attachment bt.gz to address@hidden:
Debugger entered--Lisp error: (setting-constant enable-multibyte-characters)
set-default(enable-multibyte-characters nil)
mm-find-buffer-file-coding-system("~/bt.gz")
mml-generate-mime-1((part (type . "application/octet-stream") (filename .
"~/bt.gz") (disposition . "attachment") (tag-location . 320) (contents . "")))
mml-generate-mime-1((multipart (type . "mixed") (part (type . "text/plain")
(contents . "test.\n\n")) (part (type . "application/octet-stream") (filename .
"~/bt.gz") (disposition . "attachment") (tag-location . 320) (contents . ""))))

message-send-mail(nil)
my-message-send-via-mail(nil)
message-send(nil)
message-send-and-exit(nil)
call-interactively(message-send-and-exit nil nil)
(I used the old mm-util.el instead then.)
It seems a matter of course, however I've never encountered such
an error for these months IIRC. You can reproduce the same error
now by evaluating:
(letf (((default-value 'enable-multibyte-characters) nil))
(generate-new-buffer " *temp*"))
The relevant ChangeLog entry is:
2009-09-04 Glenn Morris <address@hidden>
[...]
* mm-util.el (mm-with-unibyte-current-buffer)
(mm-find-buffer-file-coding-system):
* yenc.el (yenc-decode-region): Use default-value rather than
default-enable-multibyte-characters.
Regards,

Thanks. The patch below should have fixed it,
Stefan
