gnlcomposition with 2 wav files

[lsmithso at hare.demon.co.uk]

Hi:

    I'm trying to use gst-launch, gnlcomposition and gnlfilesource to
    concatenate wav files together.  I can get it working with one source
    file but not two.  Can someone please tell me what I'm doing wrong.
    This one works fine with either input file:
    gst-launch      gnlcomposition {\
    gnlfilesource location=file:///tmp/x1.wav media-start=0 media-duration=2000000000  start=0 duration=2000000000     } !\
      audioconvert    !  autoaudiosink
    This one fails:
    gst-launch      gnlcomposition   { \
    gnlfilesource location=file:///tmp/x1.wav media-start=0 media-duration=2000000000  start=0 duration=2000000000      \
    gnlfilesource location=file:///tmp/x2.wav media-start=0 media-duration=2000000000  start=2000000000 duration=2000000000     } ! \
      audioconvert    !  autoaudiosink
    The error is:
    etting pipeline to PAUSED ...
    Pipeline is PREROLLING ...

- Ignored:
    ERROR: from element /GstPipeline:pipeline0/GnlFileSource:gnlfilesource0/GstURIDecodeBin:internal-uridecodebin/GstDecodeBin2:decodebin21/GstWavParse:wavparse1: Internal data flow error.
    Additional debug info:

    ERROR: pipeline doesn't want to preroll.

    The wav files:

    Thanks for any help you can give.
