I'm missing some aspect of cron configuration, or perhaps some other

Look in /var/spool/cron/crontabs. That is the location of the per-user
crontabs.
If someone copied the line
17 * * * * root cd /&& run-parts--report /etc/cron.hourly
in there, you would get the error you mentioned, because root will be
interpretet as the command to run, because these crontabs have a
different format.
First, thank you and Andrei for removing the 'mystery' of where the
other crontabs are; relieved, thank you both.
/var/spool/cron/crontabs/root indeed contains exactly the error you
mention:
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.jE2KHC/crontab installed on Fri Dec 31 08:54:50 2010)

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'

Filip, the comment suggests that I shouldn't edit this file here. Do
you have any idea where, or what, its 'master' version might be? When
we first built the server, we used webmin to obtain some visibility of
system administration things, and we did use webmin's cron management
facility. We long ceased doing so, the current regular backups are
written directly into /etc/crontab, for example. But I mention webmin
in case it might have placed that warning in this file. If so, then
I'm happy changing root's crontab here because we don't use webmin any
more, anyway, and it won't change this file. But, if this file is
managed from somewhere else, changing the file here would probably be
the wrong thing to do.
regards, Ron
