From 1a679ac11ce1acff1dd97234b8b2910a2ec55ce8 Mon Sep 17 00:00:00 2001
From: Manuel Quiñones <manuq@laptop.org>

Subject: Use SugarMenuItem in the back/forward palettes

This is a fix for the GTK+3 menu palettes, and should be reverted when
the palettes are fixed.  Is the same hack as current Read activity.
