[news.eclipse.platform] "Invalid Menu Extension (Path is invalid)" at pr

["C. BOUDJENNAH" <cboudjennah@xxxxxxxxxxx>]

Hi!
I'm working on a RCP application and when I starts it I have those logs:

Invalid Menu Extension (Path is invalid): org.eclipse.update.ui.updateMenu Invalid Menu Extension (Path is invalid): org.eclipse.update.ui.configManager Invalid Menu Extension (Path is invalid): org.eclipse.update.ui.newUpdates Invalid Menu Extension (Path is invalid): org.eclipse.ui.actions.showKeyAssistHandler Invalid Menu Extension (Path is invalid): org.eclipse.ui.edit.text.gotoLastEditPosition 

I work with Eclipse 3.1.2. I really don't understand those errors since all the mentionned ids of those logs aren't used in my workspace...
Could somebody please help me???

Thanks by advance!!
