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

downloaded august 1 2015.  running on centos6. 

Please provide any additional information below.

I tried faking it with a one-liner shell script so opusenc would at least exist 
- no luck, same crash.  

Everything works fine once I comment out all the "opus" stuff in the script.   

thanks for making this available.  keeping up with all the metadata options was 
a pain in the ass.

Try revision 83 in svn. It should have fixed this issue. Let me know if it 
works for you.

Correction, I ran tests today and found the fix lacking. Try revision 84 
instead.
