Same issue here with Gutsy beta installed from scratch.
I have not changed any 'Gnome Power Manager' related settings myself, but it does not appear in my Session options, however the process gnome-power-manager is running.
Also note that this freeze/delay only occurs when I first click the power icon in the upper right, if I then cancel the shutdown menu I can then click the icon again and it appears instantly as it should.
