QtCreator using 100% of a core cpu when opening a particular qml file. Can't close the editor window after opening it

I have uploaded the affected project/file to github here https://github.com/mansona/gpodder/tree/qml-js . you need to be on the qml-js branch and open project file https://github.com/mansona/gpodder/blob/qml-js/qml-js/qml-js.pro and in the project file window open the file https://github.com/mansona/gpodder/blob/qml-js/data/ui/qml/Main.qml .

I have not confirmed this on any other machines or environments so it will just need to be tested.
