error with child variant in cart summary

[gersput]

I found an little bug with cart summary.

I have a product with two child products. The parent has a custom field Generic child variant type.
I select "Product SKU" to display in the selector the defined product SKU.

The behavior is correct in product view (but it appears duplicated).

The problem is in the cart summary view. The custom field appears but with the word "product_sku" instead its value.
