When exporting singleton types in qmldir files, qmplugindump creates invalid output and breaks autocompletion in QtCreator for those qml modules.
The exports and exportMetaObjectRevisions have invalid values.

For example:

    Component {
        prototype: "QObject"
        name: "Palette"
        exports: ["Palette -1.-1"]
        exportMetaObjectRevisions: [-1]
        isComposite: true
        Property { name: "normal"; type: "PaletteValues_QMLTYPE_2"; isPointer: true }
        Property { name: "selected"; type: "PaletteValues_QMLTYPE_2"; isPointer: true }
    }
