Can't access remote login "Configure now" session

[Michał Sawicz]

When trying the "configure now" session from Remote login help, I'm taken straight back to the greeter. The guest session itself works, though.

Seems like the apparmor profile might be causing this:

Ah, yes, the lightdm AppArmor profile needs to be adjusted to allow dbus access.

Bug 1243339 has the required changes in it.
