Here is the fix in RobotMessageBundleImpl

  @Override
  public Wavelet getWavelet() {
    if (wavelet == null) {
        wavelet = new WaveletImpl(eventMessageBundle.getWaveletData() != null ?
eventMessageBundle.getWaveletData() : new WaveletData(), this);
    }
    return wavelet;
  }

The problem with the above fix is that you have a wavelet object not connected 
to a specific wave.  It no longer 
crashes, but it's not terribly useful either.
