Having used PDFKit, I'd say that it's actually pretty simple, although  
the Tiger version has some significant limitations, especially if  
you're working with annotations.  The only crashing bug I know of in  
PDFKit, though, is related to tooltips (if you reuse a PDFView  
instance, you need to subclass it and override a private method), and  
PDFOutline's design is very broken; we worked around these problems in  
Skim.  An Apple engineer posted on the cocoa-dev mailing list that  
it's been significantly rewritten and improved for Leopard.

I don't have any problems viewing that PDF with Preview.app.  What  
exactly goes "BOOM" for you?
