QML Virtual Keyboard (input panel) segmentation faults on switch to digits/symbols page

Iheb

Hi, I'm using QML virtual keyboard on my application to enter the password. The virtual keyboard show up. However, When I go to the digits page it crashes. Here is a snippet of my code:

...
TextField{
         id: password
         anchors.top: passlabel.bottom
         anchors.topMargin: parent.width*0.02
         height: parent.width*0.078
         width: parent.width
         font.pixelSize: flickable.width * 0.035
         font.family: passlabel.font.family
         placeholderText : qsTr("Enter the password")
         color:passlabel.color
         inputMethodHints: Qt.ImhNoAutoUppercase | Qt.ImhPreferLowercase | Qt.ImhSensitiveData | Qt.ImhNoPredictiveText
         echoMode: passBox.checked ?TextInput.Normal : TextInput.Password
}
...
InputPanel {
        id: inputPanel
        z: 99
        y: parent.height*1.94
        anchors.left: parent.left
        anchors.right: parent.right
        states: State {
            name: "visible"
            when: inputPanel.active
            PropertyChanges {
                target: inputPanel
                y: parent.height * 1.222  - inputPanel.height
            }
        }
        transitions: Transition {
            from: ""
            to: "visible"
            reversible: true
            ParallelAnimation {
                NumberAnimation {
                    properties: "y"
                    duration: 250
                    easing.type: Easing.InOutQuad
                }
            }
        }
    }

I run the app with debug mode and it shows segmentation fault on this diassembler line:
