redirecting stderr - I love it to learn something new!

If I start the script

    kabcclient -L > /home/USER/contacts_hourly_backkup.vcf 2>  
/home/USER/contacts_hourly_backup.err

manually, witch exports the contacts correctly, contacts_hourly_backup.err  
contains

    kabcclient(3768)/kio (KDirWatch) KDirWatchPrivate::removeEntry: doesn't  
know "/home/USER/.kde/share/apps/kabc"

If cron starts the same script, it creates an empty  
contacts_hourly_backkup.vcf  and also an empty contacts_hourly_backup.err

So there is no error, why?
