Description Mike Thole 2010-08-23 11:03:52 PDT
WebKit should nil out the PDFView's delegate before releasing it.  This is required to fix <rdar://problem/6978204> in PDFKit.

The change is good, but the description isn’t totally accurate. The problem is that the WebPDFView is deallocated while it is still the delegate, not that the PDFView is being released while having a non-nil delegate.

Good point Dan.  I've updated the title to more accurately reflect the actual problem: "WebPDFView should remove itself as the delegate of its PDFView before being dealloced"
