	* io-ani.c (gdk_pixbuf__ani_image_load_animation):
	* gdk-pixbuf-io.c (gdk_pixbuf_get_file_info)
	(_gdk_pixbuf_generic_image_load)
	(gdk_pixbuf_new_from_file_at_size): When calling fread()
	in a loop, check for ferror() as well as for feof() to
	avoid infinite loops on directories.  (#137804, Alex Converse)
