[QGIS-Developer] Breaking default profile

[Richard Duivenvoorde]

Ok, checking my QGIS3.ini I see that the CityJSON Loader plugin I tested yesterday has some settings with 'PyQt_PyObject' in it...
See below. I think that was the problem

Removing the part below from my QGIS3.ini makes QGIS startup again.

Code for that plugin is here:

https://github.com/cityjson/cityjson-qgis-plugin

The object written to Settings is:

https://github.com/cityjson/cityjson-qgis-plugin/blob/main/core/settings.py#L6-L32

semantic_colors = {
    "RoofSurface": {
        "diffuse": QColor(255, 0, 0),
        "ambient": QColor(255, 0, 0),
        "specular": None
    },
...

So either QGIS or Qt cannot handle nested Qt objects as Settings values?

Besides asking the plugin authors to fix this, is there something QGIS can do?
As I reading settings of a plugin should not be able to crash QGIS I think?
