I'm using 7.0.3, and it just seems like some pages crash a lot. YouTube crashes, random (non flash) based games crash. This page will occasionally crash. It will do it when I'm using WebKit Nightly, and when I'm not. Since I'm using Nightly for now (might as well, it's not much less stable these days than the main one), I'll go attempt to reload Game of Thrones Ascent and let it crash out so I can get you guys a bug report.
