It happens on two different systems:

The first one is bog-standard Fedora 21:

[htd@...ara ~]$ rpm -qa | egrep 'lsblk|libblkid|nilfs'
libblkid-devel-2.25.2-3.fc21.x86_64
libblkid-2.25.2-3.fc21.x86_64
nilfs-utils-2.2.3-1.fc21.x86_64

[htd@...ara ~]$ lscp -V
lscp (nilfs-utils 2.2.3)

[htd@...ara ~]$ lsblk --version
lsblk from util-linux 2.25.2

[htd@...ara ~]$ uname -a
Linux chiara.fritha.org 4.0.5-rc1 #1 SMP PREEMPT Wed Jun 3 20:41:46 CEST 2015 x86_64 x86_64 x86_64 GNU/Linux


The second one is Arch Linux on a Raspberry Pi:

[root@...ra ~]# pacman -Q | egrep 'libutil|nilfs'
libutil-linux 2.26.2-1
nilfs-utils 2.2.3-1

[root@...ra ~]# lsblk --version
lsblk from util-linux 2.26.2

[root@...ra ~]# lscp -V
lscp (nilfs-utils 2.2.3)

[root@...ra ~]# uname -a
Linux keera 3.18.14-2-ARCH #1 SMP PREEMPT Thu May 28 07:19:33 MDT 2015 armv7l GNU/Linux

Tried to re-format the home partition on a Fedora 21 laptop with
nilfs2 and ran into the same problem as with USB memory as a samba
share on the Pi: the system tried to mount the block device rather
than the partition due to the uuid as shown in my previous email.

Thanks, Heinz.
