Unlock screen shown before system has finished suspending

Binary package hint: gnome-power-manager

When moving the mouse after clicking 'Suspend' from the session indicator, the unlock screen is shown until the system is suspended. I'd say that the unlock screen should not pop up in that scenario.

Happening on two Natty installations, not sure if g-p-m is the right package.
