adpcm file that cannot be transcoded.

I tried to transcode wave file with ADPCM data inside into mp4 audio. I was
using debian backported version of avconv (0.8.3) but this problem also exists
in latest git HEAD (just checked it).

It fails with "too big INFO subchunk" message:

$ avconv -v 9 -loglevel 99 -i test.wav

Attaching the file for investigation.
