apps such as ncftp, fdisk when hitting the backspace and delete prints
control characters to the screen instead of proper behaviour. Setting
gnome-terminal preferences to swap the backspace/del key fixes this
problem. This should be the default behaviour. This is present in the
fdisk does not link termcap or terminfo, so not surprising it doesn't understand
ncftp doesn't appear to use termcap or terminfo either.
gnome-core-1.0.55-10 and later have backspace/delete swapped by default for
gnome-terminals, as far as my testing shows.
