Can't process case classes with a curried constructor

[bytecodeguru]

description

Crashes when processing a curried case class.

Why on earth should I want to define a case class in such a way?
(see http://www.alessandrolacava.com/blog/scala-case-classes-in-depth/)

Don't know, perhaps just improving the error message for this corner case would be a nice improvement.

how to reproduce

Trying to process the following case class:

case class Curried(a: A)(b: B)

it prints the following and crashes:
