Well, there you go: 

open("/dev/sg0", O_RDONLY|O_NONBLOCK)   = -1 EACCES (Permission denied)

It's trying to access /dev/sg* devices. Add some permissions to those
and you should be fine.

By the way, do you have a real SCSI CDROM or why is it that your CDROM
is a SCSI device from Linux point of view? SCSI emulation hasn't been
fashionable since 2.6 was released.
