cron is failing to run for selinux context, but everything looks fine

[stan]

Recently, I've noticed that some jobs that are started by dwatch,
aren't starting.  If I start them manually, they start fine.  dwatch is
in cron.d, and should be running every 5 minutes, but no cron jobs are
running.  I see the following in journalctl,
Jul 28 10:07:08 localhost.localdomain crond[1192]: (root) FAILED (loading cron table)
Jul 28 10:07:08 localhost.localdomain crond[1192]: ((null)) No SELinux security context (/etc/crontab)
but when I check the security context, it seems fine to me.
-rw-r--r--. 1 0 0 system_u:object_r:system_cron_spool_t:s0  451 Jul 24  2019 /etc/crontab

Before I open a bugzilla, I wanted to check if anyone has an
explanation for this, and a fix.
