`gvfs-mount -d /dev/mapper/vg...` returns "no volume for device file /dev/mapper/vg..."

[Blah Blah]

I am trying to mount a logical volume partition (lvm2) as a device in nautilus. However, issuing `gvfs-mount -d /dev/mapper/vg...` returns "no volume for device file /dev/mapper/vg...". The logical volume is ontop of a luks container. Mounting the volume with udisks or mount does not return an issue.
