Answer 1

Lot's of folks have this problem when adding sample data. You can probably fix the problem by cleaning out the magento system logs

1. Log in as administrator
2. System -> Configuration -> System (under ‘Advanced’, bottom left) -> Log Cleaning

If you get the error again, hit the back button a few times and then try to recreate the error.

Answer 2

1) Why are you copying local.example.xml to local.xml - this is usually best done by the installer? 2) Are you importing sample data first or is it a clean install?
