qmlplugindump crashes when analyzing ChartView

I have a Qml plugin with several qml files bundled as resources. Running qmlplugindump as a post build step using CMake and it works fine.

When adding a qml file using a ChartView, the plugin itself works fine but qmlplugindump crashes with segfault.

Proposal

I know that QtCharts requires applications to use QApplication instead of QGuiApplication. So when I changed this in tools/qmlplugindump/main.cpp and added QT += widgets in tools/qmlplugindump/qmlplugindump.pro and rebuild qmlplugindump it worked fine.

Seems like an easy solution if there are not side effects.
