Phil,
It doesn't look like the exception you show in the image is really the
one from TabbedPropertySheetPage from previous stack traces you show. I
assume you have looked at the error log because I imagine the exception
you were trying to track down originally is being looked with a full
stack trace. Have you looked closely at the source code for
TabbedPropertySheetPage to see where the error there is?
