Android Qt Quick 1 App not expanded, maximized or fullscreen

Just create an empty Hello World application (in my case Qt Quick 1). When I run this application on the emulator or a phone it just creates a “window”. I expect to see the application using the whole screen like it was with Necessitas. The showExpanded(), showFullscreen() or showMaximized() seem to have no effect. Only thing that does anything is setGeometry(x,y). Then the window is resized to the geometry set with this function.

This problem seems to happen also for Widget base applications. I would consider this as citical bug as this problem makes Qt for Android unusable for releasing applications.
