if you could file a bug report at https://launchpad.net/products/jokosher/+filebug.
If you could attach the files causing the problem as well then that would be a bonus.
Created Bug #73327 I'm attempting to attach the project file to the bug. I've trimmed it down to 6MB - Will try to upload an smaller project if I can find some smaller mp3s that cause the same problem. I've also attached my dpkg listing in case that helps. good luck, Greg.
