+Subject: [PATCH] Fix a crash in KDE/Plasma with QGraphicsView. TopLevel list of items
+ was corrupted.
+
+This nasty bug was triggered when the index sort the top level list of
+items. We forgot to set the flag topLevelSequentialOrdering to false
+so when an item was removed from the top level list it was using the
+sibling index which can be not valid anymore since the list is not
+sorted by sequential order. So it let some dangling pointers in the
+list which make processDirtyItemRecursive crash the next paint event.
