Based on the log messages, there's a bad CGBitmapContext due to having a bad
CGColorSpace, and the CG calls that are failing and the order of the  
messages points
to skia::BitmapPlatformDevice as the caller
(skia/ext/bitmap_platform_device_mac.cc).  The CGBitmapContexts in there are
created using mac_util::GetSystemColorSpace() (base/mac_util.mm), which is  
new in
4.0.207.0.  (Confirm that this is a regression?)

We "warm up" mac_util::GetSystemColorSpace() during renderer startup before
bringing up the sandbox, but maybe that function is failing for other  
reasons.

If you start Chrome with --no-sandbox, does the problem persist?

Can you describe the display configuration a little bit more fully?  Color  
profiles in
use?  Custom calibrations?  Displays disconnected and reconnected since  
boot?

Could you compile (g++ displays.cc -o displays -framework  
ApplicationServices) and
run the attached program, which tries to get some display information?  This
program goes through the same motions to get the system profile that  
mac_util::GetSystemColorSpace() does in Chrome, and it also tries a few  
other things.

(I'd try the test program first, while you're still experiencing problems  
in Chrome, so
that you've got a record of it in case checking or playing with any of the  
other
settings "fixes" things for you.)
