wifi和gwibber图标从指标小程序中消失了
他们已经从gnome-panel中的指示器applet中消失了，没有问我什么也没有通知。 我怎样才能在11.04把它们带回来？ 我重新启动了，情况仍然存在。
function仍然存在，但没有图标。 只有在连接到wifi后才会出现连接图标（代表波浪的那些线条），但是从来没有图标显示没有wifi连接。 奇怪的！
编辑.-我找到了这个日志文件：
/home/user/.cache/indicator-applet-complete.log
它的修改日期是最近的，经过一些测试后，我认为每次在applet上生成事件时都会生成它。

如何解决问题，如何知道周围其他地方是否存在更多重要问题？
