The behavior of .list() for power series also produces bugs in power series
comparison. I filed a ticket and patch for this at
http://trac.sagemath.org/sage_trac/ticket/9457
but ran into unexpected problems in some of the elliptic curves code,
because the p-adics in Sage are derived from the g

Note that (x^2+1).coeffs() and list(x^2+1) do provide the desired
behaviour, so at least there's a wo
