[Felix Riemann <friemann src gnome org>]

commit 8a66150f15adb8fc1ad2bf624cfbb6a6b1997599
Author: Felix Riemann <friemann gnome org>

    Make eog-error-message-area.h a private header
    
    It's content is not introspectable at the moment and plugins cannot use
    it anyway as the function to show it in an EogWindow isn't public.
