Parameterized actions in the gallery app don't work

Currently the code is bombing out of the "data changed" callback, which means the UI components are failing to be initialized.

Fix committed into lp:unity8 at revision None, scheduled for release in unity8, milestone phone-v1-freeze

This bug was fixed in the package unity8 - 7.84+14.04.20131206.1-0ubuntu1

---------------
unity8 (7.84+14.04.20131206.1-0ubuntu1) trusty; urgency=low

  [ Michal Hruby ]
  * Ensure DashContent's ListView's currentItem is set if the model is
    not empty.

  [ Michał Sawicz ]
  * Don't generate build-deps .deb twice and allow overriding
    QML2_IMPORT_PATH in ./run.

  [ Albert Astals ]
  * Remove unused Applications/ folder .
  * Implement an 'interface' for Dash Renderers.
  * Use deelistmodel's conversion method Instead of a copy of the code .
  * Remove icons we don't use .
  * Do not start apps or go to dash on demo If you are pulling the
    launcher out while in demo mode it doesn't make sense to let you
    start applications. Besides it locks you out because it starts the
    app and the demo is still not finished so you can't really use any
    of the edges to escape Bug #1233696. (LP: #1233696)
  * Add a test for the carousel showing the preview when being clicked .
  * Fix collapsing of categories not working and the
    expansion/collapsing animation +test.

  [ Timo Jyrinki ]
  * Depend on either Qt 5.2 or libqt5v8-5-private-dev.
  * qtdeclarative5-private-dev 5.0.2-6ubuntu5 now depends directly on Qt
    V8 private headers. The remaining "qtdeclarative5-private-dev"
    dependency is enough now both when compiling against 5.0.2 or 5.2.

  [ Pete Woods ]
  * Handle optional parameterized action properties. (LP: #1256258)

  [ Andrea Cimitan ]
  * Implement an 'interface' for Dash Renderers.

  [ Michael Zanetti ]
  * Added music preview.
  * rename some parameters from desktopFile to appId as scopes are now
    changed to give us the appId.
  * unhardcode launcher's search paths for .desktop files.
  * Enable teasing of the phone greeter even though we have a
    lockscreen.
  * check if variant is valid to avoid asserting in debug mode when the
    connection to AccountsService doesn't work for some reason .

  [ Michael Terry ]
  * Add the DBus greeter API from the desktop greeter into the unity8
    greeter.

  [ Daniel d'Andrada ]
  * Dash: disable close mode when you click outside app thumbnails To
    leave the termination mode you can now just mouse/touch press
    anywhere outside the running applications' thumbnails The other way,
    which still works, is long-pressing a thumbnail once more. (LP:
    #1193414)
