What's wrong with cron?

[Lorenzo Luengo]

Hi List,

I recently configured the root alias to forward email to me, and i found 
that cron is throwing errors to my mailbox.

The subject is
Cron <root at host> root    cd / && run-parts --report /etc/cron.hourly

And the body is

/bin/sh: root: not found


It's the default system crontab, but it looks like it's skipping the 
username field and interpreting it as a command.

Thanks for any help you could provide me.
