ARGH! I upgraded to 4.6.2 (from 4.6.1), ran the tests and get the same errors as Dave.

#9032 modified Sage's .n(), and added (in two files) 

n = numerical_approx
N = n

This means that Mathematica's N[] is no longer being called - instead Sage's numerical_approx() is being called, and it can't handle certain mma objects. Furthermore the argument taken by numerical_approx is the number of bits (I think?) whereas N[50] gives 50 sig figs.

I think that the way to fix this is by adjusting precedences so that on mathematica objects, mathematica functions take priority. I also think that fixing this is beyond the scope of this ticket (which was a rewrite of ._sage_). I have created a new ticket regarding this issue: #10968
