XEmacs segfault

When trying to prepare an example for the xemacs-beta list XEmacs just
died.  I am currently on a dial-up connection and won't search for the
reference to the respective message including a backtrace but you
should be able to find it via Gmane.

I suspect the segfault is a result of the presence of shy groups in
`LaTeX-auto-class-regexp-list'.  At least it doesn't happen if I
remove the entries containing shy groups from the variable.  We should
definitely not ship 11.55 with these regexps enabled in XEmacs.
