Problem description

In the latest weekly, FreeCAD.openDocument() leads to a segfault.

Steps to reproduce:

• Open FreeCAD (I am using FreeCAD_weekly-builds-36487-2024-03-19-conda-Linux-x86_64-py311.AppImage)
• In the Python console, type FreeCAD.openDocument('/path/to/a/file', hidden=True)
• Note that it segfaults.
