[clo-devel] Update trac mercurial to 0.11.0.8 or later?

Can we update trac mercurial to 0.11.0.8 or later? I'm getting the error messages as mentioned in http://trac.edgewall.org/ticket/8897. I don't see anything bad happening, but the log file fills up pretty quickly with the error messages. I tried to update it myself using the trac admin interface to plugins, but it complains that it's already installed. Ray
