I upgraded to Ubuntu 20.04 today, and after this upgrade tracker-miner-fs seems to crash and restart contiguously; pegging my CPU at 100% until I manually kill the process.

The error I'm getting in /var/log/syslog is:

There's isntructions to permanently stop this process, but I would rather to see it work.
