Application crashes after the QQuickView has been destroyed and recreated

Can you include a simple test program that shows the bug that we can use to verify its fix?

Hi Tim! I just pushed a couple of commits which add a unit test. You can checkout the branch and copy the tests/unit_x11/ subtree from my branch onto the current trunk, and you'll see that the tst_recreateview test will fail because of signal 11.

  [ Timo Jyrinki ]
  * Temporarily disable the jokes example in order to not have
    qtmultimedia dependency from examples that is not used otherwise.
    This lessens the dependency chains of packages. It can be added back
    after Ubuntu 13.10.
  * Fix regression in qmlscene usage (LP: #1229541). (LP: #1229541)

  [ Christian Dywan ]
  * Set QCoreApplication::applicationName based on MainView. (LP:
    #1197056, #1197051, #1224126)
  * Include subfolders of Components in api check.

  [ Zsombor Egri ]
  * Organizer EDS (Evolution Data Server) integration.
  * StateSaver attached component.
  * Fix alarm status reporting, updating documentation on asynchronous
    behavior of save and cancel operations. Alarm status notification
    reports the operation the status refers to. (LP: #1226516)
  * Dialer + DialerHand components required for TimePicker. .

  [ Leo Arias ]
  * Added UbuntuUIToolkitAppTestCase as a base test case for the
    autopilot tests. (LP: #1227355)
  * Added the autopilot emulator for toggles.

  [ Nick Dedekind ]
  * Added clipping to tab bar. (LP: #1226104)

  [ Alberto Mardegan ]
  * Support re-attaching to a different QQuickView Make the plugin
    correctly handle the case when the QQuickView is destroyed and a new
    one is created: this is done by avoiding using static variables, and
    instead binding the data to the QQmlEngine, QQmlContext or QWindow
    as appropriate. . (LP: #1221707)

  [ Dennis O'Flaherty ]
  * Reword the description for easier reading.

  [ tpeeters ]
  * Fix warnings when running gallery-app autopilot tests. (LP:
    #1223329, #1223326)
  * Smarter automatic updating of Panel's opened property. Panel.open()
    and Panel.close() should be used to open/close a Panel, or when
    using a toolbar with ToolbarItems from a Page, set Page.tools.opened
    to open/close the toolbar. No API or behavior changes since the
    panel-open-close branch. Toolbar behavior changes will be done in a
    following MR.
