Not the original reporter, but I can confirm that this still affects me on latest gutsy (upgraded from feisty, no fresh install).
As a temporary workaround, I found that I can manually lock the screen and still hibernate through the "Stand-by" key on my keyboard.
Can't tell anything about suspend, because it fails -- and used to fail in feisty too, so nothing new :-(
