Crashes in the Adwaita Qt style accessing widget which there is none in QtQuick. Please report a bug against Adwaita Qt.

The reason it crashes only here is because the Colors KCM is the only one using an icon on a QtQuick Controls 2 ComboBox, everywhere else it's only text:

bool Style::drawComboBoxLabelControl(const QStyleOption *option, QPainter *painter, const QWidget *widget) const
{
    [...]
    if (!cb->currentIcon.isNull()) {
    [...]
        QPixmap pixmap = cb->currentIcon.pixmap(widget->windowHandle(), cb->iconSize, mode);
