The cups bug you link to says it got fixed in 1.5 and later 1.4; since QUantal has 1.6.x I'm marking as fix released.
This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please do steps 1 and 2 of the SRU Procedure [1] to bring the need to a developer's attention.
