Title:
  Crash when having multiple QQuickViews in a row

Status in Canonical System Image:
  Fix Released
Status in ubuntu-ui-toolkit package in Ubuntu:
  Fix Released

Bug description:
  This crash has started with Qt 5.5.1 that is more strict with sharing
  objects between qml engines.

  My guess it is something wrong with the theming engine that seems to
  be a singleton for all qml engines.

  When running the example that i will attach with

  QV4_FORCE_INTERPRETER=1 QV4_MM_AGGRESSIVE_GC=1 ./borrame3

  in xenial i get

  $ QV4_FORCE_INTERPRETER=1 QV4_MM_AGGRESSIVE_GC=1 ./borrame3 
  A
  B
  QMetaProperty::read: Unable to handle unregistered datatype 'PaletteValues_QMLTYPE_2*' for property 'Palette_QMLTYPE_3::selected'
  QMetaProperty::read: Unable to handle unregistered datatype 'PaletteValues_QMLTYPE_2*' for property 'Palette_QMLTYPE_3::selected'
  QMetaProperty::read: Unable to handle unregistered datatype 'PaletteValues_QMLTYPE_2*' for property 'Palette_QMLTYPE_3::selected'
  Segmentation fault

  while vivid+overlay (has qt 5.4) gets me
  A
  B
  C

  the backtrace of the crash in Xenial is
