Planning on getting gtk+-2.4 stable real soon: dev-libs/glib-2.4.0 x11-libs/gtk+-2.4.0-r1 x11-libs/pango-1.4.0 Ferris, Todd and i already tested without problems. A couple more testers welcome, please add up as comments, thanks.
I'd go for gtk+-2.4.1 rather than .0-r1...
Gone gtk+-2.4.1 / pango-1.4.0 / glib-2.4.1 stable. Closing.
