I had the same problem. I flushed all Cache from Magento 2 and then reindexed and now it's working.

@hvohra thank you for your report.
Could you please provide more specific cases when the issue reproduces? Maybe additional settings, product type, etc. As it may be very hard or impossible to reproduce on other environment the issue which appears "sometimes" only.

Also happens to me. I'm using Magento 2.1. It occurs during viewing cart when one of the items in the cart is set to "Out of Stock".

Replication step:

1. Add a product to cart.
2. (While product is on cart) Set added product to "Out Of Stock" in Admin
3. Going back to store site, go to Cart page (View Cart).

Result:
Fatal error: Uncaught Error: Call to a member function getPrice() on null in /Users/user/Sites/classic-spirit/vendor/magento/module-configurable-product/Model/Product/Type/Configurable/Price.php:43 Stack trace: #0 /Users/user/Sites/classic-spirit/vendor/magento/module-catalog/Model/Product.php(555): Magento\ConfigurableProduct\Model\Product\Type\Configurable\Price->getPrice(Object(Magento\Catalog\Model\Product\Interceptor))

Any update on this? I am getting this error very frequently..

I had this issue couple of months ago so and I think I was able to resolve (or get around) this issue by downgrading my php from 7 to 5.6.
