           Summary: [0.11] audiodecoder: abort when shutting down during
                    reverse playback: GST_BUFFER_DURATION_IS_VALID (buf)
    Classification: Platform
           Product: GStreamer
           Version: 0.11.x
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: t.i.m at zen.co.uk
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Steps to reproduce:

-base/tests/examples/playback$ ./playback-test 0
file:///HE_v2_AAC_44kHz_400kbps_ABR_Work_Ya_Body.m4a 

1) start playback
2) seek to middle of file
3) pause
4) open 'seek options'
5) go to speed/rate box entry and change 1.000 to -1.000 and hit Enter
6) press play (reverse playback starts up)
7) click STOP button

$1 = {mini_object = {type = 6526224, refcount = 1, lockstate = 0, flags = 0,

qdata = 0x0}, 
  pool = 0x0, pts = 18446744073709551615, dts = 18446744073709551615, duration

18446744073709551615}

So buffer appears to be valid, but duration is not set.
