Verify Error, expecting to find object/array on stack

Greetings,

why does the following cause a java.lang.VerifyError when run (Scala 2.7.7, 2.8.0, 2.8.1)? And why doesn't scalac already catch this?

----------------------
package meep

case class ParentType(parameter: String)

object ChildType extends ParentType(ChildType.something) {
  val something = "1.2.3.4"
}

object Main {
  def main(args: Array[String]): Unit = {
    println(ChildType) // <- That's line 11
  }
}
---------------------

The more interesting part of the resulting error is:
java.lang.VerifyError: (class: meep/ChildType$, method: <init> signature: ()V) Expecting to find object/array on stack
        at meep.Main$.main(Main.scala:11)
        at meep.Main.main(Main.scala)
(snip)

Any ideas?

Kind regards
