Summary0003892: Clicking on the 'Use FreeCAD material editor' button on the Model -> Material -> Material for Solid task panel crashes FreeCAD
DescriptionRef: [url=https://forum.freecadweb.org/viewtopic.php?f=18&t=34712 ]forum discusison[/url]

I'm using I'm using the 16027 appimage, and whenever I try to click on the material editor button on the Material for Solid task panel the application crashes with stack trace (below).

100% reproducible on my machine.
Steps To ReproduceCreate simple model (cube or sphere will do)
Open FEM WB
Create a new Analysis
Single click on the model in the combo view to select it
Open Model -> Material -> Material for Solid task panel
Click on 'Use FreeCAD material editor

Bang

The material editor button does work on the 16000 (py2 based) appimage. My guess would be this may be related to py3 issues.

It's not directly a FreeCAD bug. The issue is caused by Coin3d which uses its private expat library version that is not binary compatible to the system version.

On Debian this must be already fixed:
