I've got my install of FreeCAD set up with the "allow duplicate object labels in one document" setting enabled. When using the "add shapes from external file" function, it fails if the selected file contains multiple objects with the same label. I'm doing this with objects split up into multiple nested part container objects, but simple primitives from the Part workbench have the same effect. The stack trace below shows up in the report view when trying to do this.

'<' not supported between instances of 'PySide2.QtGui.QIcon' and 'PySide2.QtGui.QIcon'

Steps to reproduce:

1. create a new file
2. add 2 cubes from Part workbench
3. change label of second cube to match the first
4. save file
5. create a second new file
6. click "add shapes..." button
7. choose first file

Please let me know if there is any more information that I can provide that might be helpful.
