kopano-search: INFO - cannot open config file %s running with defaults

This is a kopano 8.6.7 from the portal on ubuntu 18.04.1 LTS.
We have a configuration file in /etc/kopano/search.cfg, but this is seemingly not found.
What is strange, even i I start kopano by hand like this:

/usr/sbin/kopano-search --config=/etc/kopano/search.cfg   -F  -l DEBUG

the result is:

2018-10-08 12:13:25,352 - search - INFO - cannot open config file %s running with defaults
2018-10-08 12:13:25,352 - search - INFO - starting search

And the config file is clearly there:

ls -l /etc/kopano/search.cfg
-rw-r--r-- 1 root root 3281 Jul 23 13:47 /etc/kopano/search.cfg

So what is wrong here?
