 Summary of the bug:
 How to reproduce:
 {{{
 % ffmpeg -y -ss 0 -i input.mp3 -codec:a libmp3lame -qscale:a 8 output.mp3
 ffmpeg version N-65810-g1b5ec6a
 built on Aug 22 2014 00:27:20 with gcc 4.8.3 (GCC)
 }}}

 Found only one specific mp3 file would cause this issue, and only when -ss
 is set to 0. I tried -ss 0.01 and it worked fine.
