now the admin interface itself does not work any more .. there should be some pre validation so we have a chance to fix it, which diving into the database...

How to fix this? I deleted all lines and got this error.

I ran into the same problem, but with setting up my store with an install/script script. Maybe a idea to replace $configuration = Mage::getStoreConfig('design/fallback/fallback', $this->getStore()) with: $configuration = Mage::getStoreConfig('design/fallback/fallback', $this->getStore()) ?: "[current]:[current]\n[current]:default\nbase:default"; In the app\code\local\Aoe\DesignFallback\Model\Design\Package.php file?
