OK, I've been able to reproduce the bug. I gonna investigate further
why we get an AttributeError, but here's a workaround already:
Your input series is a structured array, and a lot of numerical
operations choke on it. You can either transform it into a non-
structured array with .view(dtype=float), or call mov_sum on the
'inflow' field (as in mov_sum(inflows_ts['inflow'],2))
