           Summary: Some pixel test output includes DumpRenderTree warnings
                    about changing main display profile
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh

* SUMMARY
Some pixel tests (the first test each time DumpRenderTree is restarted) contain
bogus STDERR output about changing the main display profile.  This shouldn't be
included in the test output.

* STEPS TO REPRODUCE
$ ./WebKitTools/Scripts/run-webkit-tests --pixel --singly

* RESULTS
Every test will have STDERR output because a new DumpRenderTree process is
created for each test via the "--singly" flag.  This should be printed to the
console instead.

* REGRESSION
This probably started when STDERR output begin to be captured for all tests. 
This warning used to get printed to the console.

* NOTES
The warning message:

WARNING: Temporarily changing the main display color profile to
"/System/Library/ColorSync/Profiles/Generic RGB Profile.icc": the colors on
your screen will change for the duration of the testing.
This allows the WebKit pixel-based regression tests to have consistent color
values across all machines.
