As a point of information: the XpmReadFileToImage is only called if 
"HAVE_IMAGEMAGICK" is not defined, usually meaning that configure failed
to detect ImageMagick.

It's unfortunate, though, that the non-imagemagick code simply assumes that
any file it's given is an xpm and tries to read it, giving this error message.
Perhaps a little checking of file type should be done prior to the call?
