 Summary of the bug:
 When encoding the attached sample wav, the result cannot be decoded to a
 bitexact version of the original.

 On decoding, the following warning is output:
 {{{
 [flac @ 0x7f6534497100]invalid rice order: 4 blocksize 1049
 [flac @ 0x7f6534497100]decode_frame() failed
 }}}

 How to reproduce:
 {{{
 % ffmpeg -i trimmedchorus.wav -c flac trimmedchorus.flac
 ffmpeg version  N-72933-gec5164a
 built on 2015-06-14
 }}}

 I have used the reference flac implementation/tool (from the xiph website)
 to test the results. The flac tool can successfully encode and decode the
 same sample, and running `flac -t trimmedchorus.flac` on the ffmpeg-
 encoded version produces: `ERROR, MD5 signature mismatch`.
