There is a bug in 10.1.1. that causes the Terminal to logout disgracefully after having logged in (as superuser or other ordinary user) to your own machine using SSH. A "bus error" is the result.
The problem seems to be caused by "klist" that is called by "tcsh" on logout. This is a kerberos program and it calls CCacheServer. Klist crashes with a bus error. The problems will go away by commenting out (i.e. putting a # in front of it) the following line in the file /usr/share/init/tcsh/logout:
if ({ (klist -s >& /dev/null) }) kdestroy
You must do this as admin user using a plain text editor like joe or vi or emacs.
