This test fails on Apple Lion Leaks, Debug WK1 and Release WK2. But when I run the test locally on my ML machine on WK2, it still fails.
I don't know what's happening here. Maybe there are some software/hardware differences on these bots?
This is a color profile issue.

Do you know how to fix it?
No; it's an underlying system problem. Maybe changing WebCore to use sRGB rather than DeviceRGB everywhere would fix it.
7 compositing tests added in http://trac.webkit.org/changeset/148172 also exhibit this behavior. I am going to mark them flakey on Lion and ML per Simon Frasers suggestion.

I don't think that this is the same issue. Filed bug 118490 to track these separately.
