Cdemu - no connection to dbus

Question

Good afternoon!
I have tried to get cdemu to work, in order to mount a CUE image (as there is no converter from CUE to ISO as far as I know), but I'm stuck with the following error message.
[root@celestary ishina]# cdemu 0 /mnt/cdrom/installer/___.cue
ERROR: Failed to connect to CDEmu daemon: org.freedesktop.DBus.Error.Spawn.ExecFailed: Failed to execute dbus-launch to autolaunch D-Bus session
ERROR: Failed to connect to daemon!
cdemud returns the following output
[root@celestary ishina]# cdemud
Starting daemon locally with following parameters:
- num_devices: 1
- ctl_device: /dev/vhba_ctl
- audio_backend: (null)
- audio_device: (null)
- system_bus: 0
cdemud: cdemud_daemon_initialize: failed to get session bus!
Daemon initialization failed: Failed to connect to D-BUS bus.
I have conducted some research on the error message. Normally, one should start cdemud with the -s parameter, which is specified in the file /etc/rc.d/cdemud:
cdemud -s -d -n $NUM_DRIVES -c $CTL_DEVICE -a $AUDIO_BACKEND -o $AUDIO_DEVICE &>/dev/null
is the starting command for the daemon - the bus is therefore already set - but still it does not seem to work.
Has anyone got an idea, which problem I could have run into?
Regards,
cg
