I had the exact same problem with 8.04 server edition. I solved it by adding some lines to /etc/apparmor.d/usr.sbin.cupsd:
#include <abstractions/samba> /var/lib/samba/* rwk, /usr/share/samba/panic-action Pxr, -- Hardy RC CUPS crashes during printer installation with lynx https://bugs.launchpad.net/bugs/221087 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
