I wondered about that.  It has played just fine in the past on
multiple machines and programs including cmus.  I understand that
RIFF is a container format that can hold MPEG/3 and PCM data.

 $ xxd ~/tmp/music/under-dog-theme.wav | head -3
 0000000: 5249 4646 ba4d 0100 5741 5645 666d 7420  RIFF.M..WAVEfmt 
 0000010: 1e00 0000 5500 0100 112b 0000 c409 0000  ....U....+......
 0000020: 0100 0000 0c00 0100 0200 0000 0401 0200  ................

which is clearly RIFF rather than MP3.

At your nudging, a quick renaming it to .mp3 works without crashing.

So there appear to be two related issues:

  1) a file with a .wav extension can apparently be a RIFF file
  containing MPEG/3 data

  2) cmus can segfault on data it doesn't understand rather than
  gracefully logging/ignoring the problem file

So this is would no longer be "important" priority since the
footprint of the bug is far smaller; rather it's just "normal"
priority as it seems to be a narrow edge case (I'm insufficiently
familiar with BTS, but I *think* I managed to change this in a
previous email to control@).
