Comment:

 The problem is that your filter coefficients are very small, so normalize
 discard most of them. I don't think it is a bug: the problem is that your
 filter coefficients are not meaningful, nothing to do with with the length
 of your filter.

 It is a bit surprising that the change of b is changed; maybe it is better
 to emit a warning or raise an exception instead.
