Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***


After upgrade of system to python3 to 3.10.4-1 the path workbench within
freecad fails with the following backtrace:

Traceback (most recent call last):
  File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 133, in attach
    self.axs = coin.SoType.fromName('SoAxisCrossKit').createInstance()
  File "/usr/lib/python3/dist-packages/pivy/coin.py", line 491, in createInstance
    return _coin.SoType_createInstance(self)
<class 'SystemError'>: <built-in function SoType_createInstance> returned a result with an exception set
PathJobGui.ERROR: <built-in function SoFieldContainer_getField> returned a result with an exception set
SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 1389, in Create
    obj.ViewObject.Proxy.editObject(obj.Stock)

    return self.openTaskPanel('Stock')
  File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 179, in openTaskPanel
    self.showOriginAxis(True)
  File "/usr/share/freecad/Mod/Path/PathScripts/PathJobGui.py", line 156, in showOriginAxis
    self.switch.whichChild = sw
  File "/usr/lib/python3/dist-packages/pivy/coin.py", line 3998, in __setattr__
    field = self.getField(name)
  File "/usr/lib/python3/dist-packages/pivy/coin.py", line 3873, in getField
    return _coin.SoFieldContainer_getField(self, name)
SystemError: <built-in function SoFieldContainer_getField> returned a result with an exception set
