[Crashlytics #330 fix]: CPDFPageView.m is accessing an NSDictionary that is created inside CPDFAnnotation.m by TXConvertPDFObject. I added a check to make sure the return id from that method is an NSDictionary before assigning it to the info @property on CPDFAnnotation.
[Crashlytics 321 fix]: Added a guard against passing in a NULL CGRect into CGRectIsEmpty().
