Description of problem:

If I enter the release notes then follow a link in the release notes such as
"virt-manager" then I get the message "Release notes are missing.".  There is no
way to return to the release notes.

Version-Release number of selected component (if applicable):

DVD version of FC6-Pre 

How reproducible:

Every time.  
Steps to Reproduce:
1. download FC6-pre from bittorrent
2. burn to DVD
3. boot from DVD
4. verify DVD (okay)
5. press "Release Notes" button
6. scroll down to find "virt-manager" link 


Actual results:
a) message "Release notes are missing." appears
b) it is not possible to return 


Expected results:
a) either release notes for virt-manager should appear or a useful message such
as "virt-manager release notes not available offline" should appear
b) it should be possible to get back to the release notes
