I believe this is due to an error in ubuntu-defaults-builder (maybe the path to /usr/share/syslinux/themes/ubuntu-oneiric/isolinux-live/ is hardcoded?). As a temporary fix I just copied the content of /usr/share/syslinux/themes/ubuntu-oneiric to /usr/share/syslinux/themes/ubuntu-precise. When I do that, it does generate an image, but I'm not sure what other problems this could cause.
Hi Paolo Sammicheli,
