Can't restart or shut down from Kickoff?

Hi, In Fedora 17 Branched restarting or shutting down from Kickoff is no longer working. Pressing one of the buttons results in an end session (log out). At the log in screen it is possible to shutdown or reboot (via Menu-option). May be this issue is caused by the 'new way of rebooting' in systemd? Did anyone else have seen this? Are there any workarounds? Thanks, Martin Kho
