            Bug ID: 756573
           Summary: pcapparse: Crash in presence of empty packet
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

          Reporter: nicolas.dufresne at collabora.co.uk
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

pcapparse does not handle packet without a payload size of 0, and crash. I
cannot share the sample, but a simple code inspection is enough to see there is
no protection against 0 payload packet. We should probably skip does packet.

Meanwhile, I'm a bit suspicious, as for the same sample, I don't hit this
situation with 1.4. So the payload size 0 might just be indicator of another
regression. I'll try to see if I can free the sample meanwhile.
