    thumbnails: make sure to cache all mime types from gdk-pixbuf
    
    G_N_ELEMENTS() does not work for heap-allocated arrays, and always
    returns 1, so we were not actually caching all the supported mime types
    for a specific pixbuf loader after the first.
    This should also fix nautilus not thumbnailing e.g. compressed SVG
    images, as reported in [1].
