Comment:
I uploaded attachment:trac_8864-symbolic_zeta.take2.patch which also
includes a fix for the `lfunctions/dokchitser.py` doctest. I simply
replaced `zeta(2)` with `zeta(2)` to get a numeric evaluation.
I agree that `pi+1.0` looks strange, but that is not so trivial to fix. :)
FWIW, maple also seems to leave that unevaluated:
