journalctl complains about too many messages from harbour-owncloud-daemon

[nephros]

Upon startup/trigger the journal complains about rate limiting:

AFAICS there is one "Syncing Already" message per new file found.

I "fixed" it by doing:

/home/nemo$ systemctl --user edit harbour-owncloud-daemon.service

[Service]
Environment="QT_LOGGING_RULES='*.warning=false,*.debug=false'"

/home/nemo$ systemctl --user restart harbour-owncloud-daemon.service
