Summary0004311: Crash on a loft command with incorrect input (OCC bug)
DescriptionI'm experience a crash on 0.19-20406 Appimage. But with an admittedly wrong user input, but I would think that the program should complain to me instead of crashing. Lofting and adding the section that was used to start the loft will crash FreeCAD.

Thank you in advance for you time.

Note: this ticket is be tracked via OCC bugs in the bugtracker forum thread
Steps To Reproduce1. Create a new file
2. Go to part design workbench
3. Draw a simple sketch on XY plane, ie a rectangle
4. Draw another simple sketch either on a different plane, or on a parallel plane
5. select one sketch
6. click additive loft
7. Click add section
8. click on the first sketch (yes, this is wrong).
9. Click add section
10. click on the second sketch.
11. Crash.

 The bug is really in OCC (https://forum.freecadweb.org/viewtopic.php?f=8&t=45013&p=447258#p447258) -- do we want to try to work around it, at least this exact incarnation, by preventing the original profile from being selected as a section?
