Who says this is a bug ? This is a feature - there's not enough room to display all close buttons (or to read the title of the tab). And the chance to hit the wrong one would be high.

see http://kb.mozillazine.org/Browser.tabs.tabClipWidth for the preference that decides when to show the close button or not
see http://kb.mozillazine.org/Browser.tabs.tabMinWidth for the minimal width of the tab before scrolling will be used, which also plays a role
see bug 344048 for a dicussion to change the defaults for both
