Description
(This ticket was split off from #2943)
This is okay:
sage: K = Qp(13,7) sage: R.<t> = K[] sage: a = 13^7*t^3 + K(169,4)*t - 13^4 sage: a[1:2] (13^2 + O(13^4))*t
This dies:
sage: t[0:1] [boom]
The original context for this bug was along the lines of (see #2943 for more examples):
sage: K = Qp(p,10) sage: C.<t> = LaurentSeriesRing(K) sage: D.<s> = PolynomialRing(C) sage: z = (1 + O(t)) + t*s^2 sage: z * z [boom]

First comment: getslice is deprecated; it should be getitem now.
Second, there is a standard block of code for slicing...using that will make sure that things are consistent for people that understand python slices.
