I get this crash when running any application that uses cairo:

(gtk-chtheme:15702): GLib-CRITICAL **: g_scanner_input_file: assertion `input_fd
>= 0' failed
Error: Cairo does not yet support the requested image format:
        Depth: 32
        Alpha mask: 0x00000000
        Red   mask: 0x000000ff
        Blue  mask: 0x0000ff00
        Green mask: 0x00ff0000

On most suns the values for the masks when using a 24 bit display are:

 visual:
   visual id:    0x27
   class:    TrueColor
   depth:    24 planes
   available colormap entries:    256 per subfield
   red, green, blue masks:    0xff, 0xff00, 0xff0000
   significant bits in color specification:    8 bits

However we have one machine out of 20 where the masks do match what you expect:

  visual:
    visual id:    0x22
    class:    TrueColor
    depth:    24 planes
    available colormap entries:    256 per subfield
    red, green, blue masks:    0xff0000, 0xff00, 0xff
    significant bits in color specification:    8 bits
