It is surprising that /etc/apparmor.d/local/usr.bin.webbrowser.app exists, but is impotent because no other file includes it.

There are several such files on my 16.04 system:

$ cd /etc/apparmor.d && for i in local/*; do find . -type f | xargs sudo grep "include.*$i" >/dev/null || echo "$i is not included anywhere"; done | grep -v README
local/usr.bin.ubuntu-core-launcher is not included anywhere
local/usr.bin.webbrowser-app is not included anywhere
local/usr.lib.snapd.snap-confine is not included anywhere
local/usr.sbin.ippusbxd is not included anywhere
