Comment (by chapoton):
I think that I have checked fully the computation of the Dirichet
coefficients.
So well... maybe something is wrong in the parameters given to Dokchitser
program ?
{{{

sage: A = K.class_group().gen(0)
sage: from sage.modular.modform.l_series import GrossZagierLseries
sage: G = GrossZagierLseries(e, A)
