crash in 2.5.7

Fatal error. Your files have been auto-saved. Use `M-x recover-session' to recover them. Your version of XEmacs was distributed with a PROBLEMS file that may describe your crash, and with luck a workaround. Please check it first, but do report the crash anyway. Please report this bug by invoking M-x report-emacs-bug, or by selecting `Send Bug Report' from the Help menu. If that won't work, send ordinary email to `crashes(a)xemacs.org&#39;. *MAKE SURE* to include this entire output from this crash, especially including the Lisp backtrace, as well as the XEmacs configuration from M-x describe-installation (or equivalently, the file `Installation' in the top of the build tree). If you are fortunate enough to have some sort of debugging aid installed on your system, for example Visual C++, and you can get a C stack backtrace, *please* include it, as it will make our life far easier.
