Description of problem:
PDF versions of documents on docs-devel and access.redhat have duplicate author entries on the front page. Only the first author is duplicated. This issue has appeared recently, as docs published in mid July did not have this issue.

Examples:
* http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_JBoss_Portal/6.1/pdf/Installation_Guide/Red_Hat_JBoss_Portal-6.1-Installation_Guide-en-US.pdf
* https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_Developer_Studio/6.0/pdf/6.0.1_Release_Notes/Red_Hat_JBoss_Developer_Studio-6.0-6.0.1_Release_Notes-en-US.pdf
* https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_Portal/6.1/pdf/6.1.0_Beta_Release_Notes/Red_Hat_JBoss_Portal-6.1-6.1.0_Beta_Release_Notes-en-US.pdf
