Bug 1242452 - "XFCE4 Power Manager is not running, do you want to launch it now"

This bug was posted when the /etc/xdg/autostart bug was causing 
everything in that folder to fail to autostart.  The autostart bug has 
been fixed and the other shortcuts in the folder all autostart now as 
far as I know, yet this power manager bug was not fixed by it.

The workarounds posted at the time were in general the same workarounds 
proposed for all the other shortcuts in that folder.

Does anyone know why this continues to fail to autostart?  And/or have a 
new workaround?
