QML QtCreator reformats property of component type with invalid code

I have the following property defined, for example:

property Gradient greenGradient:  Gradient {
    GradientStop {
        position: 0.0
        color: "#00f03b"
    }
    GradientStop {
        position: 1.0
        color: "#3cb53b"
    }
}

In QtCreator (v3.5.0, running in Windows7) when I do a

Tools->QML/JS->Reformat File

it changes my property to the following invalid code:

property Gradient greenGradient: greenGradient: Gradient {
                                     GradientStop {
                                         position: 0.0
                                         color: "#00f03b"
                                     }
                                     GradientStop {
                                         position: 1.0
                                         color: "#3cb53b"
                                     }
                                 }

Am I doing something incorrectly by defining a Component as a property like this? Rhe QML docs state:

Additionally, any QML object type can be used as a property type. For example:

property Item someItem
property Rectangle someRectangle

Or is it just a bug in the QtCreator reformat function? I tried a few different object types with the same result. Basic types like int, color, var, string work as expected.

I think I found the answer.

The Qt5 docs are silent (or unclear at least) on this topic. However, in a Qt 4.7 doc I found this:

Such object-type properties default to an undefined value.

So, the code would have to read like this instead:

property Gradient greenGradient
greenGradient: Gradient {
    GradientStop {
        position: 0.0
        color: "#00f03b"
    }
    GradientStop {
        position: 1.0
        color: "#3cb53b"
    }
}

It's worth nothing that both the original and the modified code function the same. The modified version just gets by the QtCreator reformat function without getting messed up.
