You're right, the cut version behaves the same way.  It is about 2 seconds,
4 MB: http://dl.dropbox.com/u/18324334/baby1.avi

Behavior vs. audio bitrate:
96k --> error (also error if bitrate is not set)
72k --> freeze
64k --> success

Command line:
ffmpeg -i baby1.avi -c:v libx264 -vprofile main -preset veryslow -x264opts level=3.1:ref=8 -c:a aac -strict experimental -b:a 72k -y output.m4v
