[LAU] Cadence not starting on kxstudio / Ubuntu 16.04 - dbus error

Hi all, I couldn't find a kxstudio bug tracker (happy to be pointed in the right direction), but even after running dbus-launch, the /tmp/dbus-$whatever file doesn't exist. Any clues? antony@cubase:~$ dbus-launch DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-QQxdgcZliW,guid=5189ae91141717bf527ffc355a0a0568 DBUS_SESSION_BUS_PID=12429 DBUS_SESSION_BUS_WINDOWID=37748737 antony@cubase:~$ cadence Using Tray Engine 'Qt' (process:12609): GConf-WARNING **: Client failed to connect to the D-BUS daemon: Failed to connect to socket /tmp/dbus-qr6VFNSOMQ: Connection refused Traceback (most recent call last): File "/usr/share/cadence/src/cadence.py", line 2315, in <module> gDBus.bus = dbus.SessionBus(mainloop=gDBus.loop) File "/usr/lib/python3/dist-packages/dbus/_dbus.py", line 211, in __new__ mainloop=mainloop) File "/usr/lib/python3/dist-packages/dbus/_dbus.py", line 100, in __new__ bus = BusConnection.__new__(subclass, bus_type, mainloop=mainloop) File "/usr/lib/python3/dist-packages/dbus/bus.py", line 122, in __new__ bus = cls._new_for_bus(address_or_type, mainloop=mainloop) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoServer: Failed to connect to socket /tmp/dbus-qr6VFNSOMQ: Connection refused antony@cubase:~$ -- https:/linkedin.com/in/antgel https://resume.antgel.org/ https://about.me/antonygelberg https://antgel.org/
