The crontab command edits the files in /var/spool/cron,
not /etc/crontab.

That should solve it. The /etc/crontab (and also files in /etc/cron.d
with newer versions of vixie-cron) must include a username in the 6th
field to specify the user to run the command as.
Incidentally, I recommend putting site-specific entries in files
in /etc/cron.d, and leave the main /etc/crontab as supplied by your
distribution. Files in /etc/cron.d have the same format as
/etc/crontab. (You might need to duplicate the VAR= lines from
the top of /etc/crontab.) Note that this is very different from
the scripts (or symlinks) that are put in /etc/cron.{hourly,daily...}

Seconded. Your $PATH is probably shorter than you'd expect under crond.
Just put in an entry to run /usr/bin/env and you'll get the cron environment
mailed to you.

No need to restart crond after changing a crontab. crond reloads the
crontab automatically if it is modified.
Later,
