Internal Error when reusing my own qml component

[yinhao.qian]

I have defined my own qml type as MyIcon.qml as follows, and its only job is to display an icon.

I have another qml file named MyButton.qml, and I'm attempting to embed an icon inside the button by adding a MyIcon component.

However, after I've added the MyIcon block, this error popped up...

Does anyone know what causes this error?

What version of QtCreator are you using? It may be related to the front-end enum declaration.
