 Can you reproduce outside of firefox? Try
 
   $ fetch http://media.w3.org/2010/05/sintel/trailer.webm
   $ gst-launch playbin2 uri=file://$PWD/trailer.webm
 
 What if you build gstreamer-ffmpeg with gcc instead of clang?
 Or install the prebuilt package for freebsd 9.1 i386 ?
 
 libav-0.7.2 within gst-ffmpeg-0.10.13 also have CVE-2012-0851 and
 CVE-2012-5144 that could be avoided --with-system-ffmpeg in the port.

 This is 20121010 in ports/UPDATING issue with ariff's alsa-plugins-oss
 implementation. Try disabling ARIFF_OSS in audio/alsa-plugins.
