unity libreoffice applications have no window buttons when run from nautilus

[Rocko]

Binary package hint: unity

If I run a LibreOffice app by double-clicking on a file in nautilus, the window is shown maximized with no window buttons (see attached image showing Calc). If I run the applications directly, I do get the window buttons. Perhaps this is happening because LibreOffice isn't integrated yet into the global menu, but in any case, that shouldn't stop the window buttons from being drawn.

unity-launcher has no options to manage windows (why doesn't it?) so I can't un-maximize or minimize the window at all.
