 have.

 The file is a classic 16bits/44.1KHz WavPack file encoded with WavPack
 4.60.1.
 It can be successfully decoded by WavPack and the checksums match:

 I tried with ffmpeg:
 - 1.2.1
 - from git today (version.sh outputs N-53047-ge751481).
 I'm on Ubuntu 12.04 64bits, the configure options I use for the custom
 build can be found above.

 I have uploaded the file here (its 33M big):
