Hm, I see there might be problems with that testcase.  Here's another:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html 
  PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>WebKit bug 16075</title>
</head>
<body>
<svg version="1.1"
     xmlns="http://www.w3.org/2000/svg">
  <g transform='rotate(10)' id='b'>
  <text x='50' y='50' font-size='20' fill='red'>
    Bob
  </text>
  </g>
</svg>
<script>
g=document.getElementById('b')
g.transform.baseVal.getItem(0).setRotate(0, 50, 50)
</script>
</body>
</html>

The plain SVG draws the text "Bob" rotated at a smallish angle (10 degrees). 
The script then attempts to change the rotation to 0 so that the text should be
displayed level (horizontally).

Safari: text is rotated.
Firefox: text not rotated.

This suggests that setRotate has apparently no effect.

Is this testcase any more useful?

All this attribute synchronisation stuff is quite interesting but I don't
consider it germane to this bug.  It was a mistake to rely on the attributes
for the original testcase.

Of course, one might consider that it's a bug that it works in Firefox and not
in Safari.
