Nowadays we return early from that function instead of attempting to register the handler and then crash with a seemingly unrelated assertion deeper inside WebKit. Nevertheless, quick question: unless “G_DEBUG=fatal-warnings“ is set in the environment, that should not be the reason of the crash. Is there any chance you could run the process under GDB to get a backtrace? Alternatively, if your system has “coredumpctl” you may be able to get the backtrace from it. That would help us figuew out what the issue is here, otherwise I am afraid we won't be able to do much. Thanks for your time! 1664745 2 mcatanzaro 2020-06-20 10:32:36 -0700 No backtrace and therefore no evidence the crash is caused by WebKit. Please, see https://wiki.gnome.org/Community/GettingInTouch/Bugzilla/GettingTraces for instructions on how to report crashes. I've attached a patch in bug #209900 but there's really no evidence that is related to this issue.
