Now it works after using the k3b setup dialog. I just confirmed the standard settings there, hit burn and it burns.
It looks like k3b is not configured correctly upon installation. Maybe this is due to the fact that the CD drive was powered off, which means that /dev/cdrom was nonexistant. -- Feisty: Creating CD with k3b from .ISO file fails https://launchpad.net/bugs/76058 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
