Eclipse 未能创建视图

小弟在Eclipse 上用pydev写python程序，第一次用Eclipse，安装语言包就捣鼓了好久，安装好中文语言后问题又来了，Eclipse 提示“未能创建视图org.eclipse.ui.internal.ViewIntroAdapterPart cannot be cast to org.eclipse.ui.IViewPart ”。查看信息信息：

java.lang.ClassCastException: org.eclipse.ui.internal.ViewIntroAdapterPart cannot be cast to org.eclipse.ui.IViewPart

打开错误日志看都名为org.eclipse.ui插件的错误，哪位大侠知道这个怎么处理呀？
