I was able to figure out a simple fix but I am not sure that the results
will be correct. The fix is now in scipy CVS. See 


for details. Here is the output of Heiko's test:

>>> from scipy import signal as s
>>> s.roots([1,2,3,4])
array([-0.1746854  -1.54686889e+00j, -0.1746854  +1.54686889e+00j,
            -1.65062919 -3.31070451e-16j])

Is this correct result?
