Bug#345801: main window empty

[debbug2@danisch.de]

Package: qt4-designer
Version: 4.0.1-5

Hi,

when I start the qt4 designer, I get the full workbench, everything
seems ok. But when starting a new form and choosing a "main window",
the created window is just empty. Regarding to the docs it should have
the usual decoration such as a menu bar. It should be possible to
create a missing menu bar through the context menu. 

But there is neither a menu bar, nor does the context menu allow
this. The other decorations are missing as well. 

Any idea?

regards
Hadmut
