[Pkg-owncloud-maintainers] Bug#1012309: nextcloud-desktop: Missing Dependency to qml-module-qt-labs-platform, does not launch without it

[Krassy Boykinov]

Package: nextcloud-desktop
Version: 3.5.1-1
Severity: important

The newest nextcloud-desktop update refuses to launch its gui, because 
it needs qml-module-qt-labs-platform.
This dependency is not listed as such in the dpkg dependency tree.

Error line: [ warning default qrc:/qml/src/gui/tray/Window.qml:8 
]:qrc:/qml/src/gui/tray/Window.qml:8:1: module "Qt.labs.platform" is not 
installed

How to reproduce:
* Remove qml-module-qt-labs-platform
* launch application with nextcloud --logdebug
