I've now created a smaller an anonymized example. I tried to mail it to
myself with sendmail -t, to confirm it still crashes emacs. Mailing for
some reason didn't work, but the bounce I got back is a good enough
example: It is displayed by Gnus with a button looking like

[5. application/pdf; Brev aktieägar 131127.pdf]...

and pressing "o" on that makes emacs crash, just as withh the original
message.

Attached in gzip form. I hope emacs doesn't automagically unpack and
display the buttons for the embedded attachment when you read this in
emacs, but if it does, be careful.
