Comment:

 This appears to be a problem with (surprise) power series over p-adic
 fields:
 {{{
 sage: R.<y> = LaurentSeriesRing(Rationals())
 sage: K = Qp(5, 10)
 sage: u = y^(-1)
 sage: u(K(0)) ## Should blow up but doesn't
 0
 sage: u(0) ## Should blow up and does
 ---------------------------------------------------------------------------
 ZeroDivisionError                         Traceback (most recent call
 last)

 ZeroDivisionError: Rational division by zero
 }}}
