I'm suspicious of the: svdundo.cxx /SdrUndoInsertObj::Undo/ method - I
imagine it is removing a different object than the one it is intended to
do (which explains why the main text box in the body disappears, instead
of the header on undo ;-) - an off-by-one as it were. With this
debugging patch:
--- a/svx/source/svdraw/svdundo.cxx
+++ b/svx/source/svdraw/svdundo.cxx

I get:
UndoInsertObj: RemoveObjNum 0x969d9d8 == pObj 0x9d47390 ordinal 2 vs 0
Which explains the bad behaviour.
Quite -how- this undo list is supposed to keep it's nOrdNum synchronised
with whatever is going on in the sdpage is -totally- opaque to me; the
whole thing looks crazy from a lifecycle perspective.
It's deeply unclear to me that all this referencing by ordinal is at all
sensible - particularly vs. having a reference-counted object handle to
an immutable object.
It'd be great to have a translation of GetOrdNum vs. GetOrdNumDirect in
svx/inc/svx/svdobj.hxx - to try to grok what's going on there - if there
is a German speaker around.
