An invalid path is still being generated:

      <g class="waterway-riverbank">
<path id="area_8131246" d="M   C 0,0 529.253504988145,1512.37605217907 608.078 1725.40444523807  C 609.412910579215,1729.0121290618 627.685244301117,1728.

Don't quite follow this. waycleanup.pl seems to want to run on a .svg file, bet beziercurvehinting is run on the .osm file, so how can it run first? I tried running it on the final SVG and while it did remove many lines, it did not remove the line with the invalid path.
