Ok really strange, after running once with aa-complain, it seems to solve the problem.

In syslog I see this:

golem4 kernel: [188942.996377] audit: type=1400 audit(1507148174.867:125): apparmor="ALLOWED" operation="open" profile="/usr/sbin/cupsd" name="/proc/20273/cmdline" pid=20273 comm="cupsd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

Before that I see entries that look like this:

Note it says apparmor="DENIED"
