Crontab commands not running

I see this error on my crontab:

Dec  8 09:51:01 ikeyprod cron[29245]: Error: bad username; while reading /etc/crontab

I have verified that these commands can all be pushed manually via sudo.

-rw-r--r--   1 root     root     2.2K 2010-12-08 09:50 crontab

These commands aren't being run and I'm not sure why… I am seeing the above error though…

    # /etc/crontab: system-wide crontab
    # Unlike any other crontab you don't have to run the `crontab'
    # command to install the new version when you edit this file
    # and files in /etc/cron.d. These files also have username fields,
    # that none of the other crontabs do.
