Please write in English if possible, because the Emacs maintainers usually do not have translators to read other languages for them. Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list. Please describe exactly what actions triggered the bug and the precise symptoms of the bug: `savehist' saves something with invalid syntax and prevents emacs to start up next time.
