New issue 21659 by m...@chromium.org: CMYK JPEG rendered wrong either on  
the Mac or on Windows.
http://code.google.com/p/chromium/issues/detail?id=21659

What steps will reproduce the problem?
1. Open
http://a1.twimg.com/profile_images/229556402/Logo_Kuechengoetter_d
e_72dpi_mini.jpg
2. Look at it.

What is the expected output? What do you see instead?
Mac Chrome, Mac Safari, Windows Safari: image is black
Windows Chrome, Mac Firefox, Windows Firefox: image is orange

I'm sure that this has to do with the image decoder being used.  I think  
that
the WebKit image decoders understand CMYK and correct it to RGB, so it's
possible that the image is being corrected twice, once at load time by the
loader, and once at display time by ColorSync.

Note that the image in question will crash the renderer in Snow Leopard
until bug 21114 is fixed.

The image comes from http://twitter.com/kuechengoettin and is attached
for convenience.  Actually, this whole thing comes from bug 21114.
