After some digging, i've found that installing libreoffice-core (in case of non wanting to install the metapackage 'libreoffice') does not 'recommend' to install "libreoffice-gnome | libreoffice-kde" as it needs.
Please add "libreoffice-gnome | libreoffice-kde" as a libreoffice-core recommended dependency.
Actually i've upgaded to 5.2.3 rc1 & installed libreoffice-gnome , and the previous are gone
