Hi Barry,

but I cannot, because MailList.py stops with an uncatched exception
first. __load is called from load like this:
        for file in (pfile, plast, dfile, dlast):
            dict, e = self.__load(file)
so in __load the mtime of non-existing config.pck is asked and yields 
the exception which is not handled.
I am in no way a python developer, so I moved some lines in
the definition of __load in MailList.py (see below) and could see the web
page http://ourhost/mailman/listinfo without an error - but it was
empty! (The right thing would probably be to catch the exception).

            loadfunc = cPickle.load
        else:
            assert 0, 'Bad database file name'

        try:
            fp = open(dbfile)
        except IOError, e:
            if e.errno <> errno.ENOENT: raise
            return None, e
