I don't know how to reproduce this crash, but it occurred for me once today when I had broken WebKit so badly that resource loads never finished, started loading something, and used Ctrl+C. Backtrace attached. The problem is that resourceDataCallback always returns a success result with g_task_return_boolean(), but that's wrong if the callback was canceled. It should probably check if wkData is nullptr and use g_task_return_error() in that case.
