Finished mysql steps, fixed "known problem" with password set to OLD style, and then:
user@desktoppc:~/Desktop$ ssh -X root@smeserver /usr/bin/mythtv-setup
root@smeserver's password:

desktoppc is mythbuntu, up-to-date, with nVidia binary and xvmc. Nothing happens, just as before. No errors. So now will just ssh -X root from desktoppc (ubuntu) and not specify command, then run mythtv-setup from that command line and get same old segfault:
[root@smeserver .mythtv]# /usr/bin/mythtv-setup
