Sorry for making a opening another bug for this, but I couldn't comment to the original.
See http://sourceforge.net/tracker/?func=detail&aid=2881854&group_id=279918&atid=1188004 for the original bug.
I don't know why it worked before, but the same problems are there again.
dbus-monitor fails to run:
Failed to open connection to session message bus: dbus-launch failed to autolaunch D-Bus session: Autolaunch error: X11 initialization failed.
The (virtual) server is running Fedora 11. I have access to it over ssh only.
