This bug was fixed in the package cups-pdf - 2.4.8-1ubuntu1

cups-pdf (2.4.8-1ubuntu1) intrepid; urgency=low
* Merge from debian unstable, remaining changes:
- debian/postinst, debian/prerm: Let PDF print queue being created
automatically when installing the package
The file was renamed to CUPS-PDF.PPD by upstream, a while ago. You can
find the original file in the source tarball's extra directory.
Ubuntu needs to upgrade its postinst and postrm to match.
Debian doesn't have this issue, because they don't attempt to
automatically add the PDF queue to CUPS.
