If my understanding of this bug is correct, newer versions of WebKitGTK reliably crash Emacs, and no-one has been in touch with the WebKitGTK developers, so there are no plans to fix that.

If that’s the case, how about this attached patch to disable this feature with problematic versions of the library?
