Qt Creator crashes in Connections -element when mistyping a period instead of comma after the signal name, and adding a curly bracket after that

Code:

import Qt 4.7

Rectangle {
    width: 640
    height: 480

    Connections {
        onWidthChanged.
    }
}

When you add the curly bracket after the "onWidthChanged.", Qt Creator crashes. AFAIK happens with any signal name, ie. does not have to be an existing signal.
