Subject: 24.2.50; PNG and XPM files cannot be displayed as graphics

Hello!

At revno: 110618 I open etc/images in dired mode and type v when with the text cursor on the splash.* files. The PBM and SVG files without problem while the PNG and XPM variants open in text mode. Switching to graphics mode with C-c C-c leads to errors:

	Cannot display image: (Invalid image type `png')
	Cannot display image: (Invalid image type `xpm')

The variable imagemagick-enabled-types contains PNG PNG24 PNG32 PNG8 and XPM, imagemagick-types-inhibit is "(C HTML HTM INFO M TXT PDF)". ImageMagick's display programme can display all four splash files, identify describes:

	etc/images/splash.png PNG 275x188 275x188+0+0 8-bit sRGB 37.5KB 0.000u 0:00.000
	etc/images/splash.xpm XPM 270x217 270x217+0+0 16-bit sRGB 60.5KB 0.000u 0:00.009

Building GNU Emacs without wide ints and building as a 64-bit programme leads to the same.
