ncurses-bin is listed in the Application Manager with a size of 0 kB

Application Manager won't let me uninstall it. Using "apt-get remove ncurses-bin" won't get rid of it. And trying to "apt-get install ncurses-bin" just generates errors.

Is there a file telling the Application Manager what's installed so I can delete the (probably) bogus entry for ncurses-bin? Is there any other way to clean up this problem?
