Try something like this instead:

    try:
        z = zipfile.ZipFile(file, "r")
    except (possible creation errors here):
        print >> sys.stderr, "Can't open zipfile %s for reading" % file
    else:
        if z.testzip() is None:
            self.listBox2.Append(file)
        else:
            self.listBox3.Append(file)
        z.close()
