Description sven.jacobi 2005-02-03 13:10:22 UTC 
Load the bugdoc, there I often crash if I am deleting four pages via slide sorter. 
Four times I deleted the page 2 separately. If I was not crashing at this point,
I often crash if selecting objects from the slide.

I got following stack:

	sd680mi.dll!sd::slidesorter::model::PageDescriptor::RemoveFocus() 	C++
 	sd680mi.dll!sd::slidesorter::controller::FocusManager::HideFocusIndicator()
 + 0xe

Probably the sd::slidesorter::controller::FocusManager class does not reset the
currently focused page when it is deleted.  It tries to access it to remove the
focus indicator after it is deleted and crashes.

Duplicate, see below.
Comment 4 groucho266 2005-02-03 16:41:13 UTC 
This crash has been fixed for issue 39639 (see second comment of January 13th).
The sd::slidesorter::controller::FocusManager::HideFocusIndicator() method did
access the member pointing to the focused page without checking that it did not
hold the NULL pointer (which it did in the situation described above.)  Adding
the simple test fixed the crash.
