FreeCAD 1.0.2_11

[onuronsekiz]

After recent FreeCAD update, program was not opening.
Cleared ~/.cache, ~/.config, ~/.local/share configurations, FreeCAD opened.
But when I try to open Add-on Manager, it keeps crashing saying:

Program received signal SIGSEGV, Segmentation fault.

Here is the output when Addon Manager is clicked.

Found a temporary fix for Addon Manager bug.
Running LD_PRELOAD=/usr/lib/libexpat.so.1 FreeCAD makes the force-crash go away.
