freecad 19.1 / flatpak

[Christophe Pisteur <christophe.pisteur@fsfe.org>]

Hello,

After having failed to install freecad from an Appimage on guix system
(1), a new version of freecad (freecad 19.1) has just been realised and
proposed on flathub (2).

Unfortunately, the addon manager does not work with this version of
freecad on flathub on guix system. But it is in the addons that we find
one of the main functions until a mature version can be included in the
main project: the assembly modules (A2+, Assembly2, Assembly4). 

Here are the error messages:

1) When launching freecad from terminal:
$ flatpak run org.freecadweb.FreeCAD

2) When you click on the "install" button from the addon manager:

I tried with several addons: same results. 

Any Idea?
