Description Nalin Dahyabhai 1999-10-26 14:10:22 EDT

I'm working on a simple program that allows the user to
populate an initially-empty listbox.  If the user presses
an alpha key, newt segfaults at listbox.c:636 because
item == NULL.

Change:
if (item->text && (toupper(*item->text) ==
toupper(ev.u.key))) {
to:
if (item && item->text && (toupper(*item->text) ==
toupper(ev.u.key))) {

...and it goes away.
