For the last two weeks of nightly builds constant crashing when clicking links. The one below is repeatable. Login to Facebook. Double click a buddy on the right side as if you were going to message them Webkit will instantly crash. This is not a Facebook only bug, it's happening all the time. Something you changed in Webkit is breaking and making it completely unusable. I find it really hard to believe something like this wouldn't get caught in unit testing.
