zeta(%i-1),numer; causes an error



Dear all,

Using Maxima-5.26.0 on Mac OS X and Windows pre-built binaries,
it seems zeta() with some complex number arg generates errors.

(%i1) zeta(%i-1),numer;
BIGFLOAT: unable to convert #C(2.0 -1.0) to a CL or BIGFLOAT number.
 -- an error. To debug this try: debugmode(true);

However,
(%i2) zeta(%i),numer;
.003300120024800517-0.418155468349857*%i

I believe (%i1) case is a bug. Is there anyone working on this?
