Hello!

Several of emacs image related features have stopped working properly:
* Eww does not render images showing empty squares instead.
* When visiting an image in a buffer and pressing n to visit the next
  image the next image is either not displayed at all (showing an empty
  square instead) or a thumbnail sized version is displayed.
* Transformations such as "Fit to Window Width" or "Rotate Image" do not
  work at all. The following error message is displayed instead:
  ImageMagick error: no decode delegate for this image format `PBM' @
  error/constitute.c/ReadImage/504
  (This happens with all image formats not just .pbm)

This is independent of any init file as it still happens if emacs is run
with the -Q flag.
Everything works as it should if I roll back to the version from
2017-09-22.

I am running GuixSD on an x86-64 machine with the following config:

;; This is an operating system configuration file
;; for a "desktop" setup with StumpWM and EXWM where
;; the root partition is encrypted with LUKS.

(use-modules (gnu) (gnu packages) (gnu system nss))
(use-service-modules avahi dbus desktop networking xorg)
(use-package-modules certs emacs gnome lisp xdisorg)

  (host-name <>)
  (timezone <>)
  (locale <>)

  ;; Assuming /dev/sda is the target hard disk, and "osiris"
  ;; is the label of the target root file system.
  (bootloader (grub-configuration (target "/dev/sda")
                                  (timeout 1)))

  ;; Specify a mapped device for the encrypted root partition.
  ;; The UUID is that returned by 'cryptsetup luksUUID'.
  (mapped-devices

          (source (uuid <>))
          (target <>)
          (type luks-device-mapping))))

                        (mount-point "/")
                        (type "ext4"))
                      (file-system
