Segfault in XEmacs-21.5-b3

Here is what happens with with xemacs version r21-5-latest-beta. This happens when starting xemacs built on either of two different computers. It also happens when built with gnome+gtk, but it takes a little longer, that is the window comes up and lets you do a bit before crashing.
