      Description

      When I put a ComboBox in a Listviews delegate and the listview grows beyond the size of the parented item the applications crashes. See for example the code below. I do have a custom combobox which has nothing to do with qtquick controls and that works fine. It seems to be depended on the size of the parent (window?). It crashes with the message that some vector has gone out of bounds.

      import QtQuick 2.2
      import QtQuick.Controls 1.1
      
      ApplicationWindow {
          visible: true
          width: 640
          height: 180
          title: qsTr("Test window")
      
          Rectangle {
              width: 360
              height: 140
      
      
              ListModel {
                  id: amodel
      
                  ListElement {
                      name: "one"
                  }
                  ListElement {
                      name: "two"
                  }
                  ListElement {
                      name: "three"
                  }
                  ListElement {
                      name: "four"
                  }
                  ListElement {
                      name: "five"
                  }
                  ListElement {
                      name: "six"
                  }
                  ListElement {
                      name: "seven"
                  }
                  ListElement {
                      name: "eight"
                  }
                  ListElement {
                      name: "nine"
                  }
                  ListElement {
                      name: "ten"
                  }
      
              }
      
              ListView {
                  anchors.fill: parent
                  model : amodel
                  delegate:
                      Item  {
                      width : 100
                      height : 20
                      Text{
                          anchors.fill: parent
                          text : name
                      }
                      ComboBox {
                          height : 18
                          width : 150
                          anchors.verticalCenter: parent.verticalCenter
                          model : ["do", "I", "crash"]
                      }
                  }
              }
      
          }
      }
