Comment 37 for bug 1451728

The bigger problem this actually brings is that Mission Control
is using the accounts-sso plugin to read your accounts and make
them available to Telepathy.

But it is now failing on AppArmor because it does not allow
Mission Control to access those files at the new location.

So if I don't find a solution for that^, then I will revert this fix
and let buntu remove ktp from their archives, if they wish to
do so.
