That patch seems to have broken something in FreeCAD as i have issues 
with fonts^ and keybinds:

To reproduce:
a) Run `guix shell freecad -- FreeCAD` and notice that the texts are 
missing on the title page
b) Open a new project
1. Part Design workbench

2. Tasks and create a new body

3. Create a sketch

4. In a sketch environment use `R`-key and notice that it no longer 
works to make a rectangle
