I had the same Issue.
It can happen if you export something to have an import template, but you forget to export a mandatory field, which is related to a field, you exported.
In my example I exported "product.template" with these fields:
name, type, categ_id, (all required), image_1920, product_template_image_ids/image_1920 (to have more than 1 Image)
Now it told me "missing required value 'name' in row.."
I was confused, because 'name' was clearly there. I then realised, that product_template_image_ids/image_1920 has a related value product_template_image_ids/name, which indeed was required, but missing. I hope this explanation will help some people, which also get confused by this error message!
