HTML file showing the rendering problem

Overview:
If a div has nonzero border radius and nonopaque border color, darker strokes appear in the corners.

Steps to reproduce:
Simply open the attached HTML file in Webkit r67077 and then in Safari 5.0.2 and observe the difference.

Expected result:
See attached file 'Screenshot Safari 5.0.2.png'

Actual result:
See attached file 'Screenshot Webkit r67077.png'

Platform:
Tested on OS X 10.6.4 in Webkit 6533.18.5, r67077.

Notes:
The same problem appeared in some earlier versions of the nightlies, but I don't have numbers.
The problem does not appear in Safari 5, Safari 5.0.1, and Safari 5.0.2
