           Summary: [icydemux] broken taglist handling
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: notverysmart at gmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
      GNOME target: ---
     GNOME version: ---


This code in icydemux:

  if (GST_EVENT_TYPE (event) == GST_EVENT_TAG) {
    GstTagList *tags;

    gst_event_parse_tag (event, &tags);
    gst_event_unref (event);
    return gst_icydemux_tag_found (icydemux, tags);
  }

uses the taglist after it has been freed, resulting in a critical error during
normal ice/shoutcast stream playback.  gst_event_parse_tag does not return a
copy of the taglist, it returns a pointer to the taglist owned by the event.
