Created attachment 378388 [details] emerge --info gnome-extra/cinnamon-2.2.13: Ebuild does not mention required dependency x11-themes/gnome-themes-standard-3.10.0. After emerging cinnamon it does not work properly showing error dialog: "Cinnamon just crashed you are currently running in Fallback Mode." After manually emerging gnome-themes-standard it works as supposed.
Fixed, thanks for reporting. + 07 Jun 2014; Alexandre Rostovtsev <tetromino@gentoo.org> + cinnamon-2.2.9.ebuild, cinnamon-2.2.13.ebuild: + Cinnamon uses Adwaita from gnome-themes-standard as its default theme, and + apparently crashes if the theme is not available (bug #512612, thanks to + j.l.).
