Comment # 2 on bug 1199212 from Josef Reidinger

Hi, it looks like reason is that in autoyast profile you pass invalid script
type. Does validation of your profile pass? If you paste here your autoyast
profile, I can point you to invalid tag.

Reason why it does not fail in 15.2 is that we use code differently and
basically ignore that invalid tag, but now we have more strict code.
