[Walter C. Pelissero]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Playing around with pull down menus it dumps a core (sig 11).  Not
easy to reproduce.

Here is a backtrace from the core file:
