bug#27799: 26.0.50; SVG pictures in EWW: error in process filter, invalid image type 'imagemagick'

[Jean Louis]

Hello,

I have compiled emacs with Imagemagick exclusively
this time.

Here is how I did it:

$ ./configure --prefix=/package/text/emacs-26.0.50 --with-sound=alsa 
--with-modules --with-x --with-x-toolkit=lucid --without-gconf 
--without-gsettings --without-libsystemd --without-dbus --without-pop 
--with-mailutils


Here is the debug:

Debugger entered--Lisp error: (error "Invalid image type ‘imagemagick’")
  signal(error ("Invalid image type ‘imagemagick’"))
  error("Invalid image type `%s'" imagemagick)
  image-type("<?xml version=\"1.0\" encoding=\"iso-8859-1\"?>\015\n<!--
