    themes: minor theme fix.

    I'm actually not sure if this property is supposed to be in the gtkrc
    file. It looks like it is available only from GTK+3, and isn't it more
    of an application settings in order to select the right theme variant,
    rather than a specific theme settings?
    Anyway let's at least set the right property name.
