In 12.04, after fresh start of Ubuntu OS, the bookmarks in Nautilus works fine.
But after a while, for some unknown reason, clicking any bookmarked directory doesn't take me to the bookmarked directory.
After another while, clicking the "Bookmarks" menu, it doesn't even show the drop-down list of bookmarked directories. Actually all the other menus
Help do not respond either.
So I wonder what has gone wrong?
