There is red in Expected Image. It is not clear what the real expected rendering is. Antti, you added this test in r213064, and then it was deflaked by Chris. Is this test failing due to a WebKit bug, or a bad test?

I was able to reproduce the image failure at TOT as well as the oldest revision available to test on (r268271) using run-webkit-tests http/tests/cache/disk-cache/shattered-deduplication.html --force --iterations 50 --exit-after-n-failures 1
