--- Comment #9 from Michael Catanzaro <mcatanzaro at gnome.org> ---
Well guess what. The crash I am seeing is not even the original crash. The same webpage now produces a different WebKitWebSrc crash. I'm tempted to create a new bug report for a new crash, but... well, it's the same webpage, and the same WebKitWebSrc code, so *shrug* I'll just dump it here:
