23.0.50; savehist save invalid syntax

[Leo]

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 address@hidden 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. The error is:

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/packages/emacs/share/emacs/23.0.50/etc/DEBUG for instructions.
