qtdeclarative5-ubuntu-ui-extras0.1 doesn’t install assets

[Olivier Tilloy]

The source tree contains an 'assets' directory with two PNG images:

    $ ls ./modules/Ubuntu/Components/Extras/Share/assets
    avatar_image.jpg icon_location.png

One of which is referred to in the code:

    $ grep -rn png *
    modules/Ubuntu/Components/Extras/Share.qml:249: source: "assets/icon_location.png"

However those assets are not being installed by the package:

    dpkg -L qtdeclarative5-ubuntu-ui-extras0.1
