KDE3.5的问题

Remond

System.NullReferenceException: Object reference not set to an instance of an object
in <0x003d6> Novell.Zenworks.Gui.ZenTrayIcon:CheckUpdatesLoop ()
in (wrapper delegate-invoke) System.MulticastDelegate:invoke_void ()


请教这是什么问题？怎么解决？好像系统的remove software 和 install software 不能用了。kde下的问题!
