This is probably an ncurses bug. ncurses determines the screen size itself, and makes heavy use of the information itself (as well as passing it up to dselect so that dselect can carve up the available area). It's also possible that kermit or the remote system is putting the terminal in a weird mode and not resetting it properly. If this is the case then it's a bug in kermit or the remote system, respectively. Applications like dselect are entitled to assume that the terminal starts in a moderately sane state. If someone tells me that significant numbers of ncurses bugs are fixed in a particular ncurses version I'll download and install that and upload a new dpkg package. However, I don't want to spend any more time than I have to documenting and reporting ncurses bugs, and I certainly don't want to get into regression testing ncurses and re-reporting old bugs. Whatever it is, it's not a bug in dselect :-). (I'll leave this bug open, of course - when the problem has been identified and solved, could the person responsible please close it).
