The output is not "broken" or "nonsensical". It is logically correct, although not presented in the simplest form possible.
The condition if n == 3 and n != 0 could be simplified to if n == 3. There is a difference between "could be simplified" and "is completely nonsensical".  
But yes, please report it on SymPy tracker, since the simplification is incomplete; a better result would be Piecewise((0, Ne(n, 3)), (-1.0, True)).
