--- Comment #2 from Michael Catanzaro <mcatanzaro at gnome.org> ---
The only practical way to debug this is to bisect to find the commit that broke it. Any chance you're able to try your own build from git and see if you can reproduce the crash there? If so, then it's bisectable.

$ git clone git://git.webkit.org/WebKit-https.git WebKit

Once you've cloned (it will take a while, but don't do a shallow clone because we need the history), follow the instructions "Building WebKitGTK from a release tarball" at [1], NOT the instructions "Building WebKitGTK from git" below that. Except do use git, not a release tarball. I know that's confusing, but it will be fine. ;)

If you have trouble, then I can try to bisect it for you with the access to your machine that you offered, but that will go onto my TODO list with no ETA, so quickest way is to try yourself. My guess is that a bisect would require about 10 builds, probably can be done in a long morning or afternoon on your hardware.
