            Bug ID: 140069
           Summary: [GStreamer] Disable gst-plugin-scanner if seccomp
                    filters are enabled
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at igalia.com

If seccomp filters are enabled, any child processes we create are doomed if they try to use a trapped syscall: the child will receive SIGSYS and dump core. There appears to be no way around this.

Fortunately, the gstreamer developers had mad prescience and provided us with a way to move plugin scanning in-process, so we don't need the helper binary at all.
