          Severity: Normal
          Priority: P1
         Component: SVG

I found this with my fuzzer in the latest Chrome 1.x release, so the stack
dumps and such contain no symbols, which is why I'm not attaching them.
However, I can repro in latest Chrome 2.x ToT build. The repro is simple and
reliable, so you should have no problem tracking down the root cause.

Repro:
<SCRIPT>
  polyline = document.createElementNS("http://www.w3.org/2000/svg",
"polyline");
  polyline.points.appendItem(null);
</SCRIPT>
