Various discussions on the Internet suggest that the solution would be to make the back-end directory's permissions more restrictive. Sadly, while this indeed makes the warnings in the CUPS logs disappear, it also has the sad side-effect of disturbing the operation of other CUPS back-ends. Anyhow, I've discussed the situation with the rest of the CUPS team and we came to the conclusion that reverting this change and letting CUPS fix the permissions itself in postinst would make more sense. I've already uploaded a new cups-pdf that reflects these changes. The only part that remains is for CUPS to fix the permissions. Martin-Éric
