Debian 10

gnome-documents: Settings schema 'org.freedesktop.Tracker.Miner.Files' is not installed

There is a missing dependency in debian 10 gnome-documents packages. This message shows up in syslog after every gnome login if you have :

I get in this situation because I manually remove tracker-miner-fs. It's job is feeding lots of different buggy parsers with your files silently, a serious security risk for me. tracker-extract seems not required then, removed too.

It happens also if directly starting gnome-documents from console: 

lpouzenc@lud-hp1:~$ LANG=C gnome-documents

(org.gnome.Documents:26169): Gjs-WARNING **: 16:35:39.656:
 JS ERROR: Error indexing the getting started PDF: GLib.Error tracker-miner-manager-error-quark: Filesystem miner is not active

(org.gnome.Documents:26169): GLib-GIO-ERROR **: 16:35:39.714:

Trappe pour point d'arrêt et de trace (core dumped)
lpouzenc@lud-hp1:~$
It will probably creates coredump files: 
lpouzenc@lud-hp1:~$ ls /var/lib/systemd/coredump/
core.gnome-documents.1000.ffffffffffffffffffffffffffffffff.5183.1628935228000000.lz4
core.gnome-documents.1000.ffffffffffffffffffffffffffffffff.9507.1628948576000000.lz4
Either go for apt remove --purge gnome-documents or try to re-install parts of tracker until gnome-documents is happy.

I believe this is fixed in debian 11 because dependency list has been updated in the package. I didn't fully test that for myself (debian 11 not released at time of writing).
