[Dirvish] Problem with dirvish-locate on debian jessie

[a_n_o_n_y_m_o_u_s at web.de]

I have the following master.conf
-----------------------------------
bank:
         /mnt/backup/daily/dirvish

exclude:
         lost+found
         proc/
         core
         .Trash-1000

Runall:
         pi:home
         pi:etc
	mac:home
	mac:etc
	ubuntu:home
	ubuntu:etc
-----------------------------------

This is my "pi/dirvish/etc.conf" example
-----------------------------------
client: root at pi
tree: /etc
xdev: true
index: gzip
image-default: etc/%F_%H
-----------------------------------

This is an example of the content
-----------------------------------
$ ls /mnt/backup/daily/dirvish/pi/etc/2016-10-26_08/
index.gz  log  summary  tree
-----------------------------------

So although the index is there this is the result
-----------------------------------
$ sudo dirvish-locate pi:etc 'hosts'
0 matches in 0 images
-----------------------------------
