Title:
  SlotsLayout with Column as mainSlot: endless loop when resizing view
  so that Column has negative width

Status in Canonical System Image:
  New
Status in ubuntu-ui-toolkit package in Ubuntu:
  In Progress
Status in ubuntu-ui-toolkit package in Ubuntu RTM:
  In Progress

Bug description:
  With a simple code such as

  import QtQuick 2.4
  import Ubuntu.Components 1.3
  import QtQuick.Window 2.0

  Window {
      SlotsLayout {
          id: slotsLayout
          onHeightChanged: print("SlotsLayout height",height)
          width: parent.width
          mainSlot: Column {
              onHeightChanged: print("COlumn height",height)
              onWidthChanged: console.log("Column width", width)

              Rectangle {
                  id: rect
                  width: parent.width
                  onWidthChanged: console.log("RECT WIDTH", width)
                  onHeightChanged: console.log("RECT HEIGHT!", height)
                  height: 5
              }

          }
      }
  }

  
  Or something similar (http://archive.is/N0jnM), when resizing the view horizontally to only use few pixels, an infinite resizing loop starts and the view freezes.
