I found the solution here: http://mysupport.dizzion.com/Knowledgebase/Article/View/46/0/profile-redirection-issues-with-taskbar---profileunitypersona-management. When the Default User profile is copied out, a couple folders are missing within that default profile (I'm wondering if this comes from using Sysprep with the CopyProfile switch in unattend.xml). To fix the problem edit your template by adding the following folders - "User Pinned" and "Taskbar" as follows.
C:\Users\Default\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\
C:\Users\Default\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\Taskbar
Shut down. Snapshot. Recompose. Done.
It looks like this happens on View Persona Managment and Liquidware Labs ProfileUnity profiles.
