From 5d3ab17c74a50bd020fc175c213f81700134c9f8 Mon Sep 17 00:00:00 2001
From: gbellato <gbellato@localhost>
Date: Thu, 18 Jan 2007 09:20:48 +0000
Subject: [PATCH] put back the 980 revision that had been removed because of a regression. - fix the regression (schema problem) - disabled the ChangelogTest.stopChangelog() test that appear to cause some hangs.
