Comment 4 for bug 1349087

So, looking on 10.04, I find C-h v image-load-path says

image-load-path's value is
("/usr/share/emacs/23.1/etc/images/" data-directory load-path)

So, I now try on my pristine 14.04 and I find the value to be void. Looking in /usr/share/emacs/23.1/etc/images/ I find it's a load of .xpm files, and that's there's a similar set in /usr/share/emacs/23.4/etc/images/ on my 14.04 installation. So, I put the line (setq image-load-path "/usr/share/emacs/23.4/etc/images/") in a buffer, make it a region and use M-x eval-region on it. After that C-x m produces what I expect, ie a mail buffer looking like

To:
Subject:
From: <me>
---text follows this line---

ie, what I expect. Putting in some sensible fields, eg an email address and subject, I appear to be able to send mail. So, all that remains to fix this bug is to find out why the default install of emacs didn't set image-load-path, and fix that.
