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).
