The xpra proxy is trying to setup a dbus service that you can use to
interact with it, the dbus bindings try to execute "dbus-launch" which
is failing to execute due to the X11 initialization error.
Either fix your environment so that the user running the proxy can run
"dbus-launch" without getting those errors, or use: --dbus-launch=no
--dbus-control=no
