The error in the subject line comes from running the attached code which defines two monic integral polynomials in QQ[x], both irreducible and defining the same number field of degree 44, and trying to find a root of the second in the number field defined by the first:
Trying K.is_isomorphic(L) works (and returns True. so these polynomials really do define the same field. (They are the characteristic polynomials of Hecke operatrs T2 and T3 acting on an irreducible space of modular forms for Gamma_1(25)). That is strange since I would have thought that testing this involves finding roots of one modulo the other. K.embeddings(L) also fails with the same error.
