Comment 7 for bug 508073

Sorry, was in a bit of a rush to get the comment posted. So that people don't have to travel to the dupe, the bug is in detecting whether or not any power manager at all is running. Since it uses getXconsole from /etc/acpi/powerbtn.sh without sourcing it, it always fails to find a power manager and will always fall back to the shutdown command. Here's a debdiff based of of Philip's work to fix this.
