It looks like your profile didn't get updated since the chromium profile in the apparmor profile package contains this rule:
unix (getattr, getopt, setopt, shutdown) peer=(addr=none),
Can you attach /etc/apparmor.d/usr.bin.chromium-browser? (It sounds like maybe you modified this file, upgraded, and chose not to use the new profile. You probably have a /etc/apparmor.d/usr.bin.chromium-browser.dpkg-new that you'll have merge in the changes).
