[katello] Problem Syncing Capsule

Hi all,

After successfully creating a katello 2.0 capsule (on CentOS 6.6), I am
unable to synchronize content. I've ensured the capsule has an environment
attached and I've recently published new content. However, whenever I
either publish content or manually sync from hammer, I get the following
error. Any ideas would be appreciated.

RestClient::InternalServerError: 500 Internal Server Error
