internal system error

[molly]

Lately I've been getting very frequently (let's say every quarter of an hour) a warning about an internal system error, specifically a Package Manager error. In detail:

Error Type: 
Error Value: 'NoneType' object is unsubscriptable
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2316, in 
    main()
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2313, in main
    backend.dispatcher(sys.argv[1:])
  File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 600, in dispatcher
    self.dispatch_command(args[0], args[1:])
  File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 508, in dispatch_command
    self.get_updates(filters)
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1769, in get_updates
    self._check_init()
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1996, in _check_init
    self.yumbase.repos.doSetup()
  File : /usr/lib/python2.5/site-packages/yum/repos.py, line 71, in doSetup
    self.ayum.plugins.run('postreposetup')
  File : /usr/lib/python2.5/site-packages/yum/plugins.py, line 178, in run
    func(conduitcls(self, self.base, conf, **kwargs))
  File : /usr/lib/yum-plugins/rpm-warm-cache.py, line 32, in postreposetup_hook
    cmd = commands[0]
Does anybody know what I should do to fix it? 

Thanks in advance,
molly
