Pitivi fails to start

It appears a recent update broke pitivi. While I am not great at reading python errors, I believe that the error is caused by a library incompatibility.

Gdk-Message: 08:44:27.571: Unable to load tcross from the cursor theme
 Traceback (most recent call last):
 File "/usr/lib/python3.9/site-packages/matplotlib/backends/backend_gtk3.py", line 43, in  <module>
    cursors.SELECT_REGION: Gdk.Cursor.new(Gdk.CursorType.TCROSS),
TypeError: constructor returned NULL

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