[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@email-addr-hidden:~$ dbus-launch
DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-QQxdgcZliW,guid=5189ae91141717bf527ffc355a0a0568
DBUS_SESSION_BUS_PID=12429
DBUS_SESSION_BUS_WINDOWID=37748737

antony@email-addr-hidden:~$ cadence
