FYI, 'sudo aa-complain cupsd' doesn't change anything, so a kernel update might be the cause. I have installed two kernel upates since the release of lucid, 2.6.32-22 (lucid-updates) and 2.6.32-23 (lucid-proposed). The bug occurs with bot updates.
andschuster, could you try to reboot to 2.6.23-21 and reproduce the bug there?
