Xfce4: quit does not work

[Carlos A. M. dos Santos]

Hello,

I have a brand new machine with 7.0-STABLE-200805 AMD64 (GENERIC
kernel). Today I installed all the required packages using "pkg_add
-r", including xfce-4.4.2. Now if I run "startxfce" I get the desktop
environment running but neither the "Quit" option of the desktop menu
nor the quit button of the panel work. I got the same error starting
XFce by means of GDM and by means of XDM. Running xfce4-session-logout
by hand does not work too.

I have another machine with xfce-4.4.1_1 and it do not have this
problem, so I suspect that this is the same bug that was already
reported here:

     http://bugzilla.xfce.org/show_bug.cgi?id=1109

Is there any known fix/workaround? Any help will be welcome.
