[winswitch] Bug with dbus

[Pierre Wulles via shifter-users]

Hello, I,m still trying to set up an architecture with xpra over 3
machines, client, server and proxy, when I use:
xpra proxy :13 --bind-tcp=0.0.0.0:10000 --tcp-auth=allow --daemon=no
to set up the proxy, I have the following error:
2018-07-24 16:37:02,764 dbus server error

Thank you very much,

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

Cheers,
Antoine
