x11-themes/oxygen-gtk installs some config files into /usr/share/themes/oxygen-gtk/gtk-2.0 - argb-apps.conf - gtkrc - icons4 - kdeglobals - oxygenrc As these files can be used for system wide configuration purposes, they should be config protected.
Good point although it should be rare case when changing those files is necessary. CONFIG_PROTECT added anyway. Thanks for reporting. *oxygen-gtk-1.0.1-r1 (20 Jan 2011) 20 Jan 2011; Maciej Mrozowski <reavertm@gentoo.org> -oxygen-gtk-1.0.0.ebuild, -oxygen-gtk-1.0.1.ebuild, +oxygen-gtk-1.0.1-r1.ebuild: Remove old, add CONFIG_PROTECT to fix bug 351614, install some misc files, sort dependencies, add debug and doc USE flags.
