Bug#969230: freecad crashes on wayland when opening FCStd files

[Pedro Ângelo]

Package: freecad
Version: 0.18.4+dfsg2-5
Severity: important
Tags: upstream

Dear Maintainer,

   * What led up to the situation?

On Debian testing, under the Sway window manager (which is Wayland-based), it
is not possible to read or write FCSstd files on Freecad. To reproduce:

 * use a wayland-based window manager
 * open a shell and execute `QT_QPA_PLATFORM=wayland freecad`
 * try to load an FCSstd file

this issue is known upstream:

https://forum.freecadweb.org/viewtopic.php?t=33359

the proper fix requires a patch recently merged to coin3d:

https://github.com/coin3d/coin/pull/404

I flagged this as important because it makes the package unusable on native
Wayland setups. A workaround is to set `QT_QPA_PLATFORM=xcb` before starting
Freecad.
