It would seem that there must be two dbus-1 service files with the
same Name= key. What does 'grep org.kde.kuiserver /usr/share/dbus-1/*/*' say?

[Hint: You can run the generator for debugging at any time with
mkdir /tmp/x; /usr/lib/systemd/systemd-dbus1-generator /tmp/{x,x,x}

Add SYSTEMD_LOG_LEVEL=debug or strace or similar for more detail ;) ]
