*** Bug 124636 has been marked as a duplicate of this bug. ***
I realise now that the version bump is not needed and you guys maintain the GTK overlays, etc (http://bugs.gentoo.org/show_bug.cgi?id=124088 and http://forums.gentoo.org/viewtopic-t-437869-highlight-.html), but please include the WACOM patch in your next release - http://bugzilla.gnome.org/show_bug.cgi?id=142536 for the GTK bug track. I've posted the patch on a linuxwacom bug track for Gentoo aswell (still no reply).
bumped in portage
http://bugzilla.gnome.org/show_bug.cgi?id=142536 <- The patch has been accepted - as GTK-2.8.13 isn't in official portage (only gnome-experimental) if it does get into portage before 2.8.14 (which will include this patch) could you please include it for WACOM users!
