Code review comment for lp:~andreas-pokorny/unity-system-compositor/expose-powerkey-state-and-screen-toggle-controller-interface

What's going on here? Looks like the bug is still open to some extent (read the final comment on the remaining error states).

I'm not sure this is the correct approach...shoul the telephony service be listening to the powerKey event or rather should it be listening to the power state change event from powerd or whomever
