求助：Debian nm-applet图标不出现！
我刚装上Debian4，可是一会儿显示网络连接的图标不见了。以下是错误信息：
$nm-applet
** (nm-applet:3149): WARNING **: <WARNING> nma_dbus_init (): nma_dbus_init() could not acquire its service. dbus_bus_acquire_service() says: 'Connection ":1.12" is not allowed to own the service "org.freedesktop.NetworkManagerInfo" due to security policies in the configuration file'

如果使用sudo nm-applet,则图标又出现了。可是只要退出该命令，则又不见了！
有人知道如何解决吗？
