Apple Senior Product Manager, Joe Schorr, posted this note on the Apple forums today:

"As many of you know, last week's Security Update caused printing problems for users of Aperture 2 on Leopard. A new version of this Security Update was posted this week, and it resolves this issue. What you need to download is Security Update 2008-002 v1.1. Note that this update has the same name as last week's, but the version number has been changed from 1.0 to 1.1."

I had received some mail on this issue, and am happy that the fix came quickly.
