[mythtv-users] Shutdown function isn't working anymore

[mythtv at pdebrabander.nl]

i've Setup mythtv 0.17 with Alex' RPMs on FC2, and now shutdown function
isn't working anymore.
When i select shutdown only mythfrontend stops, but the computer is not
shutting down. With 0.16 and FC1 the poweroff command with the shutdown
function in the menu was working.
