Status in OpenObject Server: Fix Released

Bug description:
Environment:
-------------------------------------------------
OpenERP Web ; Version 6.0.0-rc1
Ubuntu 8.4 ; Linux scubuntu 2.6.24-28-server #1 SMP Sat Oct 16 18:09:42 UTC 2010 x86_64 GNU/Linux
Python-2.7
Google Chrome and Firefox

Latest versions of all dependencies (Let me know if you need me to list them with their versions)

Problem:
-------------------------------------------------
1. I installed OpenERP 6.0.0-rc1
2. I clicked on the "Start Configuration" button that appeared when I first logged in
3. I hit next (I've tried several times and it doesn't matter if I use the simple or the extended Interface)
4. I hit next (again, I have tried by entering in valid data and have tried with the defaults)
5. I select/check all of the applications and any of the "Industry Specific" applications and then hit "Install"

I then get the Following:

An Application Error has been reported.
Let me fix it
Fix it for me

I click on Let me fix it and I get the following:
