Seems like the culprit is Apparmor : root@iutm-inf-ghost2:/var/log# tail -300 /var/log/kern.log
Mar 25 16:37:46 iutm-inf-ghost2 kernel: [ 9297.515512] type=1400 audit(1364225866.005:10922911): apparmor="DENIED" operation="capable" parent=1 profile="/usr/sbin/cupsd" pid=17770 comm="cupsd" pid=17770 comm="cupsd" capability=29 capname="audit_write" "aa-complain /etc/apparmor.d/usr.sbin.cupsd" helps, as a temporary workaround.
