I understand that this issue is far from being important, but this is going to be the fourth unreviewed file in this issue. I noted all your comments to me and fixed the patch accordingly, but ever since November I'm the only one who posts something here. I pinged the issue about 4 days ago (after a month of utter silence) and still didn't get any response. Could someone review the latest patch (the one I attach to this message - traceback_rev.diff) or at least say what's wrong with it (or with this issue, or with something else)?
