[winswitch] Bug with dbus

[Pierre Wulles]

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
Traceback (most recent call last):
