I think the problem is that there are actually two constructors with the same signature. The one is defined with default arguments and the other has the same signature as the one with default arguments when you leave all default arguments out. I assume that this confuses the Scala compiler and only works if you've specified the right types or at least one of the parameters with a default argument.
