At least one output file must be specified

The audio track is not in the resulting file.

What version of the product are you using? On what operating system?

0.7-rc5, it works as expected with rc3 (didn't have rc4 around)

Please provide any additional information below:

I tried this with two different very simple files which were also created with 
ffmbc (a while ago) and both with the same result so I believe it should be 
reproducible easily. Let me know if you can't and you need a file, the I'll put 
it in dropbox.

Can you please upload the file somewhere ? It's always better to have the file.

I made that exact file available to you via dropbox. Please don't share it, 
since it's a private file. If you do need a sample that can be used publicly I 
will produce one.
