Gramps v5.2.3 om Mac Ventura  
When installing (upgrading) FamilyTreeView v0.1.15 I got this error message in [Addon Manager](https://gramps-project.org/wiki/index.php/Gramps_5.2_Wiki_Manual_-_Navigation#Using_the_Addon_Manager):

```python
ERROR .: Unhandled exception
Traceback (most recent call last):
  File "/Applications/Gramps.app/Contents/Resources/lib/python3.11/site-packages/gramps/gui/widgets/styledtexteditor.py", line 698, in __set_fallback_icons
    icon = tool_button.get_child().get_child()
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'get_child'

```

However, the update went thru and all seems to work ok
