Comment 8 for bug 1016103

Ok, I checked with our security team and they say it's due to your non standard /homes (i.e the "s" at the end), for such setups you need to tweak the apparmor rules as indicated on https://wiki.ubuntu.com/DebuggingApparmor#Adjusting_Tunables

Setting as invalid, it's not really a bug, non standard setups require some tweaking in configurations
