Nope, I can run the files just fine manually, it's just the upstart script. The one thing I did do was edit banana using vim for windows, so maybe it's screwing up the line endings or something. I'll try with a 'vanilla' banana and not edit it before copying it across.

EDIT: Nope, still not working. I hate to ask this but have you tried using the files from your zipfile? Are you sure that the zip program isn't doing something strange to the line endings?
