Description of problem:

Hello,
when I try to suspend with gnome-power-manager
It notify some unknown error, in .xsession-errors it is

** (gnome-panel:2941): WARNING **: Could not ask power manager to suspend:
Method invoked for Suspend returned FALSE but did not set error

If I run:
dbus-send --session --dest=org.gnome.PowerManager --type=method_call
--print-reply --reply-timeout=2000 /org/gnome/PowerManager
org.gnome.PowerManager.Suspend

the error message:
Error org.freedesktop.DBus.GLib.ErrorError: Method invoked for Suspend returned
FALSE but did not set error

The suspend method itself works perfect if I run it by hand with
pm-suspend

lshal output:
  power_management.acpi.linux.version = '20070126'  (string)
  power_management.can_hibernate = true  (bool)
  power_management.can_suspend = true  (bool)

I tried to set policy in /etc/dbus-1/system.conf
to allow any user to do anything, but it does not help.

My smolt profile number is
e16b4e38-a73b-4323-bcb1-91938db0f084

Version-Release number of selected component (if applicable):
Fedora 7 fresh install on new system partition (with all updates) and the
home directory from previous FC6 (with all preferences)
