KDE: "leave" options don't work

I'm running 12.04 with multiple DEs. I did a search and found this relevant thread, but it's old. I followed the link to this page but I can't seem to find notifybysound.cpp to try the fix. Have things changed since then?

In the meantime I've been using sudo shutdown -r now but it's the elephant gun to my moth. I just want to be able to log out/restart/shut down the normal way.

Thanks,

Well, apparently it was just a bug and they seem to have fixed it, so I guess I can mark this "solved" even though it sort of solved itself.
