I have just succeeded to manually trigger the bug, even on all my machines where it was not appearing on startup (that means the (n-1) machines that had not any problem) by adding some niceness.
sudo nice -n 19 sh -c '/etc/init.d/cupsys stop && /etc/init.d/avahi-daemon stop && sleep 5 ; /etc/init.d/avahi-daemon start ; /etc/init.d/cupsys start ; sleep 3 ; ps auxww|grep [c]upsd'
