Daniel, have you tried simply applying the 6.0 patch to your OpenERP 5.0
server?
You can find the patch by going to the revision mentioned in comment #4:

Title:
  safe_eval prevents workflow execution with Python 2.7

Status in OpenERP 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:
