Hi,

I was trying to send the audio part of a video file to a softphone. A MPEG file
I own produces a SIGSEGV when I create a pipeline

cat /root/video.mpg | gst-launch -v fdsrc fd=0 ! decodebin ! audioresample !
alawenc ! rtppcmapay ssrc=1234 ! udpsink host=<address> port=<port>

It does not crash when I replace decodebin with mpegdemux ! mad ! audioconvert
:

cat /root/video.mpg | gst-launch -v fdsrc fd=0 ! mpegdemux ! mad ! audioconvert
! audioresample ! alawenc ! rtppcmapay ssrc=1234 ! udpsink host=<address>
port=<port>

So I suspect decodebin is the culprit. It still crashes when I place a fakesink
rather early in the pipeline, so the RTP encoding is most likely not the
problem.

I ripped the file off some website, so I can't attach it here due to
copyright/terms of license problems. 

Please send me a mail if you wish to deal with this.
