So it's apparently the right dbus-daemon which starts the at-spi service.

But for some reason XOpenDisplay(NULL) failed to connect to the Xvfb
started by xvfb-run, and all the rest comes from this. Do you have xauth
installed and does xvfb-run properly set things for X applications to
connect? You might want to check with

$ xvfb-run -a /usr/bin/xlogo
