> 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?
