Bug#787034: Further details: .wav files causing problems

[Tim Chase]

The directory in question has a variety of media including .mp3,
.ogg, and .wav so as an experiment, I created an isolated directory
and copied one media file into it until it crashed.  While the .mp3
and .ogg worked fine, a single .wav file was enough trigger the
segfault.

  $ rm -rf ~/.cmus ~/tmp/music
  $ mkdir -p ~/tmp/music
  $ cp $MEDIA_DIR/under-dog-theme.wav ~/tmp/music
  $ file ~/tmp/music/under-dog-theme.wav
  /home/tim/tmp/music/under-dog-theme.wav: RIFF (little-endian) data,
  WAVE audio, MPEG Layer 3, mono 11025 Hz
  $ cmus
  :add ~/tmp/music
  [Segmentation fault]

I can provide the .wav in question if needed (though there might be
copyright considerations).  It doesn't seem to crash on every .wav
file as I have others that play just fine.  Based on file(1) output,
the ones that play fine are 

RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono
44100 Hz

(the rate varies, so some are 44100 Hz while others are half that)
