puppet not running regularly on quantum build slave

I found that puppet wasn't running regularly on the quantum build slave (50.57.114.73).
 * had updated a manifest for the slave to add a package, 3 days later package still wasn't there
 * logged in to slave, verified package wasn't here
 * last entry in /tmp/manifest.log was 6 days prior
 * reviewed Cron job - think I spotted an error in the flock command there

Cron job looks to be created by Puppet, but couldn't find the relevant manifest to make a patch to it. I foudn I could invoke Puppet remotely, did so - that replaced the existing crontab with the following:

# HEADER: This file was autogenerated at Tue Aug 30 17:14:30 +0000 2011 by puppet.
# HEADER: While it can still be managed manually, it is definitely not recommended.
# HEADER: Note particularly that the comments starting with 'Puppet Name' should
# HEADER: not be deleted, as doing so could cause duplicate cron jobs.
# Puppet Name: updatepuppet
*/15 * * * * sleep $((RANDOM\%600)) && cd /root/openstack-ci-puppet && /usr/bin/git pull -q && /var/lib/gems/1.8/bin/puppet apply -l /tmp/manifest.log --modulepath=/root/openstack-ci-puppet/modules manifests/site.pp

Since then, has been running every 15 min.

This bug is simply to track/ask the question: Any other hosts still out there with a broken (i.e. using Flock incorrectly) puppet crontab?
