This problem was repeated again after turning on PC!

I am also affected after upgrade from bionic to eaon.
Same StacktraceTop

Maybe you all can already tell this from the crash report, but here's what syslog says when this happens. As a previous poster noted, it happens every time the system boots up, and it started immediately after upgrading to Eoan (from Disco, in my case).

I am also seeing this issue.

I am also having this error, and the output is identical to the original poster, and also happens at each restart.

I got the same error just after upgrading to 19.10 from 19.04. It didn't happen again.

Seeing this on each startup as well. The log looks like that posted in comment 10.

Seeing this on each startup as well.

I'm also getting this error on every boot on my Dell XPS 13 (Model 9380) with Ubuntu 19.10. It has all updates installed. The error also shows up after sleep and at apparently random times as well.

Also getting this on every startup.

This affected me too. I'm using Ubuntu 19.10 on a Dell XPS 13 9360 with all updates installed. After some research I decided to disable tracker-miner-fs temporarily.
You can disable tracker-miner-fs too by using these commands:

/usr/bin/gsettings set org.freedesktop.Tracker.Miner.Files crawling-interval -2
/usr/bin/gsettings set org.freedesktop.Tracker.Miner.Files enable-monitors false

Afterwards you need to cleanup the database to reclaim some lost space on the disk using:

echo y | LANG=en tracker reset -r

While this doesn't fix the problem, it at least doesn't show me the error messages on every startup.
Hopefully someone can fix this problem soon.

I'm also getting same error message every time y boot my Alienware 15 R2. After upgrading to Ubuntu 19.10 from 19.04. All updates installed.

I am also getting this exact error. I just upgraded from a pretty recent 19.04 installation to 19.10 and the bug occurs after every boot. All updates installed.

carloroepke's workaround succeeded for me, but I used the gconf app for a GUI to change the crawling and enable-monitors values.

/org/freedesktop/tracker/miner/files/

I have 4 different machines, all four have different hardware, and I get this crasher every time at bootup, on all four of them since upgrading to 19.10.

Happens at every boot.

The assertion seems to be in this file:
https://gitlab.gnome.org/GNOME/tracker/blob/master/src/libtracker-miner/tracker-file-system.c

The issue is due to a corrupted database, you can delete it and let tracker index again as a workaround
$ rm -rf ~/.cache/tracker

The solution(workaround) worked well for me.

oups ! the error is on return...sorry for the too quick comment.

I am also affected after upgrade from Ubuntu 18.04.4 LTS Bionic Beaver to Ubuntu 20.04 LTS Focal Fossa.

After running $ rm -rf ~/.cache/tracker the issue is resolved.
Thank you for the workaround.
