This looks like the scheduler is not auto-creating its IPP cache which also updates the printers.conf file with the Filter lines.  I am *quite* certain this works for the standard CUPS distribution (otherwise we'd get a lot more complaints about Mac OS X upgrades), so I'd guess you are running into a Debian/Ubuntu-specific bug.
