That won't work with puppet's cron provider, unfortunately. It will only
remove cron jobs it identifies as one of its own.
To be more specific: It uses a commented header to identify the cron
job. As you see, the hour and minute does not need to be specified to
remove the cron job:
,----[ Existing crontab before puppet ]
| s...@mavis:~ :) $ crontab -l
| # m h dom mon dow command
| 08 08 * * * /home/ssm/bin/update-schroots
`----
,----[ Add new crontab with puppet ]
| $ puppet -e 'cron{"update-schroots": command =>
"/home/ssm/bin/update-schroots", minute => fqdn_rand(59), hour=> fqdn_rand(23),
ensure => present }'
| notice: /Stage[main]//Cron[update-schroots]/ensure: created
| s...@mavis:~ :) $ crontab -l
| # HEADER: This file was autogenerated at Mon Aug 02 11:33:18 +0200 2010 by

| # HEADER: While it can still be managed manually, it is definitely not
recommended.
| # HEADER: Note particularly that the comments starting with 'Puppet Name'
should

| # m h dom mon dow command
| 08 08 * * * /home/ssm/bin/update-schroots
| # Puppet Name: update-schroots
| 25 17 * * * /home/ssm/bin/update-schroots

You could, instead, use a definition to remove a line matching your
commands in the crontab file with a define like the one found at
