`PlotWidget`: `ZeroDivisionError` on resize while ignoring constraints

[pnmatt]

On my app, I have some PlotWidgets (plotpy.plot.plotwidget.PlotWidget) inside several QWidgets with QGridLayouts. On the last QWidget, I have overloaded minimumSizeHint() to return QSize(100, 100), ignoring the size constraints of the PlotWidgets.
When resizing the widget window, and when the height or width of the widget reaches 0, plotpy raises a ZeroDivisionError.

Traceback:

Traceback (most recent call last):
  File "C:\...\python-3.8.10.amd64\lib\site-packages\plotpy\plot\base.py", line 712, in resizeEvent
    self.apply_aspect_ratio()
