sudo in emacs ansi-term segfaults after upgrade to karmic

Binary package hint: sudo

After upgrading jaunty to karmic, sudo gives a segmentation fault, but only within an emacs ansi-term. To reproduce my setup:

 $ emacs -nw (emacs version is 23.1.50.1)
 M-x ansi-term (/bin/bash, enter)
 $ sudo -s
 Segmentation fault

Nothing appears in /var/log/messages and this doesn't seem to be any of the existing sudo segfault issues. Also,

 $ echo $TERM
 eterm-color
 $ export TERM=emacs
 $ sudo -s (now it works)

Sharing this info for what it's worth.
