Summary: polyroots fails for polynomial

                         -2.0237466230245725e-4*x+3.849560052117091e-6$

allroots(p);

polyroots(p,x);

Don't know why, but polyroots fails to find any root of this polynomial.  There's nothing really special about it that I can see, other than all the roots are real.
