Hi all!
Just in case anybody runs into the "libreoffice has no menubar"-problem: installing dbus-x11 will bring the menubar back.
An other thing that you might run ointo: libreoffice by default uses x11 fallback interface, which is exceptionally ugly. You have to install "libreoffice-gtk3" and set "SAL_USE_VCLPLUGIN=gtk3" in .profile to get a reasonably usabe GUI. (libreoffice-qt5 breaks any kind of printing from libreoffice)
