Thanks. Note that we haven't released sage-3.2.3 yet, so "sage
-upgrade" won't get you that version. We intend to release it today
or tomorrow, and post binaries within 2-3 days.

I tried this in 3.2.3.final and it works fine:
sage: a,b = matrix(QQ,[[0,1],[-4,0]]).eigenvalues(); a,b
(2*I, -2*I)
sage: a in RR
False
sage: b in RR
False
so perhaps you should upgrade?
