bug#13867: 24.3.50; reading certain emails containing images in mu4e causes segfault

[Paul Eggert]

To make this easier to reproduce, can you pull the image
in question out of the email, and visit it separately?
If that makes emacs -Q dump core, then we can try to
visit the image ourselves.

You might try a "bzr up", as there was a recent fix for an
ImageMagick core dump in trunk bzr 111937 (see Bug#13846 in
<http://bugs.gnu.org/13846>) and this is later than the
version you built.

Also, can you please try building Emacs without optimization
and with debugging symbols, and generating a backtrace for that?
