Sidebar items won't go away

hi

Some items in my "Places" sidebar have been trashed but I can't seem to get rid of the items in the sidebar.Contrary to "live" items which I can erase with control + click "Remove from sidebar", control + click on the non existent items only give me "Open SIdebar Preferences" and of course the prefs don't help me to erase those items either

So any other solution ?

thx
