"Mage registry key "product" already exists" Error When Trying To Mass Delete Products

Question

I have this strange error when I'm trying to mass delete products from Magento admin (catalog>manage products). When i select multiple products and choose Delete option from "Actions menu it deletes only first product from selected list and gives me error "Mage registry key "product" already exists".

Any ideas what could be causing it and how to fix it?

You can use Mage::unregister($key) function to resolve the registry error if you know the key.
