I'm surprised that dbus-launch is being invoked, my only guess is that
a GTK+ module is using DBus and that is attempting to initialise.

However, if X11 initialisation is failing then you won't have much
luck with depexp - it's a X11 application.  If you're running on a
server without X11 then you can't use depexp.  By using "bitbake -g
busybox" you'll get the dependency graph in .dot format, which you can
browse on another machine using something like XDot
(http://code.google.com/p/jrfonseca/wiki/XDot).
