Failed to start Tracker metadata extractor

Hi everyone:
When I setup NIS and NFS client, I got the following errors from journal -xe

--
-- Process 3993556 (tracker-extract) crashed and dumped core.
--
-- This usually indicates a programming error in the crashing program and
-- should be reported to its vendor as a bug.

Then after the process restarts, it happens again!
Is there any way to debug this?

Can you try (as standard user).

rpm -q tracker
rpm -q tracker-miners.x86_64

if that works

tracker3 daemon --list-miners-available
tracker3 daemon --list-miners-running
tracker3 status
