Mutt 1.5.18 "could not copy message"

[mcba]

Mutt says "could not copy message" whenever I am sent emails with attachments by a particular person. The relevant headers (as revealed by "pine") are:

User-Agent: SquirrelMail? MIME-Version: 1.0 Content-Type: multipart/mixed;boundary="----=_20080703110649_28315"

---

Content-Type: multipart/alternative;

boundary="8627fsu_trap_51382_94601130708002_=----"

Content-Transfer-Encoding: base64

--8627fsu_trap_51382_94601130708002_=---- Content-Type: text/plain Content-Transfer-Encoding: 8bit

...TEXT IS HERE...

--8627fsu_trap_51382_94601130708002_=---- Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit

...MORE TEXT... --8627fsu_trap_51382_94601130708002_=------

---

Content-Type: text/html; name="untitled-[1.2]" Content-Transfer-Encoding: 8bit Content-Disposition: attachment; filename="untitled-[1.2]"

...MORE TEXT...

---

Content-Type: image/jpeg; name="APT_adjust_focus.JPG" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="APT_adjust_focus.JPG"

...JPG DATA...

and so on.

Any help greatly appreciated. And a big "thank you" for mutt!

I also see this with 1.5.18. There are plenty of SquirrelMail? users out there, so a more graceful handling of this type of mail (even if it's violating RFCs) would be very gratefully received, thanks!

I wonder if changeset [f5fe657f0633] helps with this. Can you try a current nightly (see http://dev.mutt.org/nightlies/) and report how it handles these messages?

Hi Brendan,

Yep, that fixes it! I just tried mutt-20081116.tar.gz.

The other improvement I noticed is that the header cache is working
much more quickly that before. It only takes a fraction of a second to
get back to where I was with an inbox with 6500 messages.

Both improvements are very welcome!

Thank you,
regards, Michael
