Gnome-2.24: No way to shutdown or reboot through menu or GDM

[Andrew W. Nosenko]

Since update to Gnome-2.24 the "shutdown" dialog (as called through
menu System -> Shutdown at panel) lost the "Shutdown" button.  Waiting
for 60 secs doesn't results in the shutdown (as adverstized in the
dialog message), but jusrt closes this dialog instead and does nothing
more.

Tested under regular user, which is a member of "wheel" group, and
uder the root user.  Results are the identical.

The "Shut down" button in GDM greeter/chooser just results in the
"Fail to shutdown" message window and does nothing more.

All the same applied for "Restart"/"Reboot" -- the same conditions,
the same results.

Session started from GDM.  Arch: FreeBSD-7.0 amd64.

Under Gnome-2.22 all this have worked fine.

Does anyone observes such behavior also?
