In /etc/profile.d/tcsh-settings, it sets an alias for cwdcmd that clobbers the xterm titlebar. The instructions at the top of the file say to make modifications in /etc/profiles.d/local.csh or in ~/.tcshrc. Unfortunately, that doesn't work, as the dammage is already done by the line "cd ." immediately after setting the alias. This leaves modifing the tcsh-settings file as the only solution.
could be fixed by the patch in bug #89295
note to self: done
Fixed in 6.14-r1
