Comment 2 for bug 418994

I was wrong, it crashes every time I try to run X through ssh forwarding. Here is the GUI message:
Traceback (most recent call last):

    launcher = TweakLauncher()

GError: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Failed to connect to socket /tmp/dbus-tblDbvz0Uv: Connection refused)

And here is the terminal output:
