- speculative fix for <rdar://problem/
5509989> CrashTracer: [USER] 1 crash in Safari at com.apple.WebKit:
-[WebPDFView(FileInternal) _updatePreferencesSoon] + 56
The crash is probably due to messaging a dealloc'ed dataSource ivar. The dataSource ivar isn't retained
by this class, but should be. (It is retained by WebHTMLView, e.g.).
* WebView/WebPDFView.mm:
(-[WebPDFView dealloc]):
release dataSource ivar
(-[WebPDFView setDataSource:]):
retain dataSource ivar
