Digging around that error, i've found http://askubuntu.com/questions/48994/unity-files-folders-lens-cant-find-anything

and did:

sudo zeitgeist-daemon --quit

 extension-collection.vala:123: Skipping SearchEngine (disabled)

The latest message "Skipping SearchEngine (disabled)" is quite a surprise, and wonder what it really means.

Feedback since the #4 commands:

after a cold reboot, the fts.index have been rebuilt, and journalctl no more show the reported bug error.

That's it

[Superman ha Muerto (superman-ha-muerto)]

I think I got this error because I've restored a full backup from an older system (Ubuntu 14). I think that this fts.index was restored from a previous version of Ubuntu and therefore the problem started because of this.

I tried deleting the directory ~/.local/share/zeitgeist/fts.index/ and the error still shows up on 16.04.2
