cron does not run on strict policy-2.x

[Shintaro Fujiwara]

Hi,
I have a sever strict-policy newest package,
but my cron fails.
When I see /var/log/cron,
ENTRYPOINT FAILED
line I could get.

/etc/crontab has 
system_u:object_r:system_cron_spool_t.

I have two FC5 strict-policy server and 
both fails on cron,although anacron runs
faily fine.
