The problem is in the mandelbrotStepsToInfinity: method; there you create
a new Complex number with "new", rather than "new:imaginary:", thus the
instance variables "real" and "imaginary" aren't initialized. You should
either cause "new" to initialize these variables, or change the creation
code to use "new:imaginary:".
(the same problem exists in the other arithmetic methods).
