Crash stack trace https://forum.freecadweb.org/viewtopic.php?f=8&t=37757&e=1&view=unread#p327901 It appears to by caused by handling QAbstractItemDelegate::closeEditor signal twice. Once inside PropertyItemDelegate::editorClosed via slot connection where the editor is closed/destroyed, the other in PropertyEditor::closeEditor() which tries to access the destroyed editor. This patch removes handling of closeEditor signal in PropertyItemDelegate.
