F18 - laptop suspends twice under Xfce

[Maciek Borzęcki]

Has anyone noticed anything weird regarding laptop suspend under F18 and
Xfce 4.10? 

I've god a good old T60 here, and since upgrading to F18, whenever a
suspend is triggered through ACPI (lid closing, Fn+suspend), the laptop
suspends twice. What happens is that right away after closing the lid
laptop goes to suspend (really fast, I don't recall suspend being this
fast ever). Then after opening the lid, the screen shows for a second
and it goes to suspend again.

Observations so far:
1. it does not happen under gnome 3
2. it does not happen if I trigger suspend from software (xfce ->
applications -> log out, or pm-suspend)

I've restarted xfce4-power-manager with --debug, and it seems that
something else triggers suspend in kernel, even before
xfce-power-manager gets the relevant event about lid being closed.
