latest gtk2 version, works fine for me. nothing really new inside the ebuild, since one for 1.3.4 didn't apply any patches or magic hacks :) only thing i had to add was SRC_URI (sourceforge) because galeon is not going to be included in new Gnome release. regards, artb.
Created attachment 13048 [details] galeon-1.3.5.ebuild (update)
thanks for the report. i've bumped the galeon 1.3 series with your changes.
