            Bug ID: 221489
           Summary: [WPE][GTK] web-process-terminated signal not emitted
                    when bubblewrap sandbox is enabled
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org

The web-process-terminated signal is not emitted when a web process crashes with the bubblewrap sandbox enabled, which breaks Epiphany's web process crash error page. I have no idea why, since all we do is check whether the IPC socket is still open. Maybe there is some bug (perhaps even a kernel bug?) causing that to not work.

The child process, bwrap, does die as expected, and we need to rework the code to check process exit status anyway in order to fix bug #193117, so any fix for that issue would probably fix this too.
