Added a test expectation in http://trac.webkit.org/changeset/138910.

Is this a recent regression?

Possibly.

Not in the last couple days at least:

I don't know how far back the flakiness dashboard goes.

[Ojan Vafai]

If you click "show all runs" the flakiness dashboard will show the last 500 runs on each bot. And you can click on the box to see the date for that run.

So, as far back as we have recorded, which is currently 12/14/12.
