bug#5441: 23.1.91; rmail error "Malformed quoted-printable text"

[Kenichi Handa]

While reading mails by rmail, I encountered "Malformed
quoted-printable text" error.  When I try to delete that
message by typing 'd', the same error was signaled.

The reason is that rmail-show-message-1 calls
mail-unquote-printable-region, and
mail-unquote-printable-region signals that error.  For a
workaround, I applied this patch to rmail-show-message-1,

and successfully deleted the problematic messages.

But, I'm not sure that is the right fix.  Perhaps we should
attach some text or text-property to indicate this error.

Was the quoted-printable part indeed invalid?  Can you show an example
of that invalid part?  Maybe we should fix
mail-unquote-printable-region to cope with such cases.

I don't know, I've already deleted those messages because
they were spams.  I'll check the contents when I get such a
message next time.

I'm not sure.  I've just noticed that the function accepts
the argument NOERROR.  So, perhaps rmail-show-message-1
should call mail-unquote-printable-region with that arg t.

I've just got such an error mail.  Save the attached file,
for instance, as "qperror", and do C-u M-x rmail RET qperror
RET to reproduce the problem.  As I don't know the detailed
spec of QP, I can't judge it's surely an error or no.

bug#5441: rmail error "Malformed quoted-printable text"

[Ulf Rehmann]

[-- Attachment #1: Type: text/plain, Size: 328 bytes --]

Hi. I have seen the same error several times, mostly with spam.

Attached are two versions of a (kind of minimal) email which provokes
that error. 

They differ by

   diff TTT1 TTT2
   18a19
   > Content-Transfer-Encoding: quoted-printable

The file TTT2 produces the error, while file TTT1 seems to behave well.

Regards
Ulf
