(forked from #146563) From the RC1 changelog [http://www.xfce.org/release_notes/4.4rc1_changelog.html] Session Manager (xfce4-session) * Add support for HAL to shutdown/reboot the computer. Must be enabled explicitly using --with-shutdown-style=hal to configure (Bug #2046). there is no "hal" USE flag in xfce4-session,though. From the RC2 changelog [http://www.xfce.org/release_notes/4.4rc2_changelog.html] Desktop Manager (xfdesktop) * Use d-bus bindings directly for all interaction with d-bus to avoid xfdesktop's UI freezing while waiting for responses. d-bus is now required at compile time for file icons However, dbus is not listed among the requirements of xfdesktop.
Fixed in CVS, thanks for reporting!
