The following sequence kills gnome-terminal and xterm (havne't tried others): $ export TERM=gnome $ export TERM=gnome-rh90 $ export TERM=gnome $ export TERM=gnome-rh90 $ export TERM=gnome $ export TERM=gnome-rh90 <crash>! lemme know what additional information you would like to debug this. I'm attaching strace output while doing this in xterm.

Nalin... I think this is a gnome-terminal/vte bug
It is not the terminal, but the bash shell itself. It even happens in a text VT. zsh seems unaffected by this problem.

Created attachment 99597 [details] termcap-116934.patch Try this patch.
I have just tried this with gnome-terminal/xterm with todays Rawhide tree (upgraded from a fc2test3 install), and this is not reproducable. libtermcap-2.0.8-37.1 xterm-179-6.EL gnome-terminal-2.6.0-2 termcap-11.0.1-18.1 libtermcap-devel-2.0.8-37.1 This might be closable as RAWHIDE.
I have the exact same versions as in comment #5, and I can still reproduce this crash. Will need to test patch a little later.
Patch works for me. Can reproduce the crash on FC1 with libtermcap-2.0.8-37.1 (rebuilt from rawhide), but can't reproduce it with the patch from comment 4 being applied.
Confirmation for yesterday's Rawhide. Needs eight (8) times toggling $TERM between gnome and gnome-rh9 to crash. Patch fixes it.
OK, with the standard .bashrc in /etc/skel, this cannot be reproduced, as in comment #5. However, using a custom .bashrc crashes gnome-terminal (or the tab that it was running in). The patch in comment #4 works to fix this. On FC1, the crash does happen with a custom .bashrc, but with a fresh user I still cannot reproduce the crash.
Fixed package has been built as 2.0.8-38.
fixed in rawhide-latest (as of 08/05/2004) using libtermcap-2.0.8-39. Please re-open this issue if the bug re-appears.
