Hi all,
Sage-5.0 fails to compute the Gauss sum of Dirichlet character of
conductor 1009:

sage: p=1009
sage: p.is_prime()
True
sage: DG=DirichletGroup(p)
sage: chi=DG.gen()
sage: chi
Dirichlet character modulo 1009 of conductor 1009 mapping 11 |--> zeta1008
sage: g=chi.gauss_sum()

Is this known issue? chi.gauss_sum_numerical() works fine.
regards.
