Got some help on irc from burek. As per his recommendation I updated to
latest git build and got past these errors.
However amerge segfaulted instead and burek created a bug report here
http://ffmpeg.org/trac/ffmpeg/ticket/1400

I tried amix and that worked. I'll have a look at pan now since you
recommended not to use amix.

Thanks for your help.

Atli.
