I can imagine they won't use it very much, or perhaps not at all. I think Skim only uses -[PDFPage attributedString] for AppleScript. And as for -[PDFBorder dashPattern], they may not use it because you cannot control that in Preview (it's set to a fixed value). So apparently Preview just got lucky not to hit the problem spots. Or more likely, they weren't discovered by Apple because Preview didn't hit them. I am actually more worried about the 10.5 bug, because it's far less likely to be fixed soon. Also, for the attributedString I have a workaround (by leaking it), but not for the others.
