Package: mutt
Version: 1.5.18-6+b1
Severity: normal
Hi,
I have encountered a little bit awkward behavior when mutt opens
attachment in external viewer (according to mailcap). The problem is
caused by mutt creating read-write temp file for the attachment which can
be misinterpreted by viewer to enable editing as well.
I do understand that viewer is not supposed to enable editing, but this
is happening. Just as one example consider OpenOffice and doc/odt
attachment. I ended up with lost changes (2h of work) because I thought
that mutt would keep the file if it had been changed after opening.
If the tmp file was read-only from the beginning then even editor
wouldn't allow me to edit it.
I have hacked my use case by the following simple patch:
--- mutt-1.5.18.orig/attach.c 2009-05-11 17:22:38.000000000 +0200
+++ mutt-1.5.18/attach.c 2009-05-11 17:24:24.000000000 +0200

+ chmod(tempfile, 0400);
use_pipe = rfc1524_expand_command (a, tempfile, type,
command, sizeof (command));

I don't consider it to be the real fix, but maybe it can help with
resolution.
Thanks in advance.
