 Martin's script trick is a good one here if recompiling with
 `--enable-trace' is too cumbersome. Hauke sould try something like:
 
 env SHELL=/bin/csh xterm -g 80x25 -ls -e /usr/bin/script
 
 then see who's sending '\r\e[3g' followed by '\eH' at each of the tab
 positions. But, one has to explicitly set rows and lines with stty after
 every window resize because script doesn't trap SIGWINCH.
