Since http://trac.webkit.org/changeset/58524/ these have been failing:
the last one is not related to SVG. I guess it's Adam Barths change, that removed the need for custom code in the NodeIterator bindings.
What do you mean the first two are failing? Can I see the diffs somewhere?
What's the full state of Chromium/SVG now? Only _two_ SVG errors left after the big rebaseline?
