TOC Rendering Fails after Content Restore from Backup

Here are the following steps to reproduce this bug:

1. Create a test page
2. Using the following Wiki markup as an example:

   {toctable} \r
   \r
   {contentbylabel:labels=vmware -linux|showLabels=false|showSpace=false|max=100|operator=AND|sort=title}\r

This behavior only happens from Confluence 3.3 until 3.4. Confluence 3.2 and below is not affected.
