This and the related commit in xfce-utils broke it again for me.
After I changed the ck-l-s command in $prefix/etc/xdg/xfce4/xinitrc as
Mike suggested yesterday on the Xfce users list, it worked fine. I
could reboot/halt my system and also mount devices (USB stick) in my

Now, with the change above, I can't do any of these things.
xfce4-session-logout only offers Logout, reboot and halt are disabled.
Also mounting my USB stick doesn't work with this change.

I don't use any display manager, just plain console login as in good
old days.

I see that the above change seems more correct but it just doesn't work

At session startup, I also get the following messages in
~/.xsession-errors. Though not sure whether they are related:

(polkit-gnome-authentication-agent-1:1978): GLib-GObject-WARNING **:
cannot register existing type `_PolkitError'

(polkit-gnome-authentication-agent-1:1978): GLib-CRITICAL **:
g_once_init_leave: assertion `initialization_value != 0' failed

Has anyone else similar problems or is just me?

Btw, all this happens on Debian Testing.
