bug#4937: 23.1.50; PGP/MIME signature doesn't work

[Torsten Bronger <bronger@physik.rwth-aachen.de>]

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.  If you can, give
a recipe starting from `emacs -Q':

When signing an email in Gnus with C-c RET s p and trying to send it,
Emacs reports "apply: Wrong type argument: stringp, 48" and the email
is not sent.

The same procedure with "C-c RET s o" (plain PGP) works, however.


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'.
For information about debugging Emacs, please read the file
/usr/local/share/emacs/23.1.50/etc/DEBUG.
