Is this actually a sage error? It could be that these are roots in the ring Qp(3, 20) = Z/3^20 though, but that would be very confusing.
Probably yes, I just wanted to keep track of it so we can workaround?

So when does this cause a problem? Because I think sage already complains if there is not enough precision to determine whether or not two roots are different.
Well in the example I gave it loses 4 / 20 digits, which is a psychological problem for me, if my roots are of ((x+5)(x+4)(x-13)x(x-3)*(x-4)) I want to see -5,-4,13,0,3,4 as my roots.
Well, then I would suggest to file this with sage, and not here.
