+;; Workaround: The call to `mm-display-part' below triggers a bug in
+;; Emacs 24 if it attempts to use the shr renderer to display an HTML
+;; part with images in it (demonstrated in 24.1 and 24.2 on Debian and
+;; Fedora 17, though unreproducable in other configurations).
+;; `mm-shr' references the variable `gnus-inhibit-images' without
+;; first loading gnus-art, which defines it, resulting in a
+;; void-variable error. Hence, we advise `mm-shr' to ensure gnus-art
+;; is loaded.
