Comment 14 for bug 81227

Interestingly, when I use the power-off key on my keyboard (which sends the exact same keycode I think) it does not show up twice.

My guess is there are two keycodes that will trigger a 'shutdown' and some computers are sending both. Linux is catching both and therefore giving two shut-down screens.

Its just a wild guess, but its the only explanation I could come up with, that takes into account that it always happens twice (never three times, never once) and that keyboards do not trigger the same effect.

Any one else have any speculation as what-is-causing this?
It is a regression b-t-w, shouldn't that be in the bug summery?
