            Bug ID: 763503
           Summary: tsdemux can crash on shutdown
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: thaytan at noraisin.net
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

When tsdemux calls mpegts_base_deactivate_and_free_program, it frees the
program structure, but leaves a pointer to it in the global program hash table.
If that program number isn't reused in the new PMT, then the bogus pointer will
be used when resetting the demuxer going to READY.
