Steps to reproduce: 1. Open gnome-terminal. 2. At the command prompt, $ while true ; do cat /etc/termcap ; done 3. Resize the terminal window. 4. The terminal region doesn't resize. Occasionally, a crash may be observed. This is a pathological worst-case scenario, but it happens to me all the time opening mutt (which enumerates messages as it opens my (large) mbox.)
