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 <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

BUG DESCRIPTION:
When I type the following:
C-x 8 RET greek letter alpha
and press TAB, I get several choices for the greek letter alpha
variants. But I'm unable to type anything into the minibuffer (neither
SPC nor any character) -- Emacs just doesn't accept the input. If I
press RET at this point, I get the error message "ucs-insert: Not a
Unicode character code: nil".
I tried with "emacs -Q" (no init files), and I still get this
incorrect behavior.

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
d:/Progs/emacs/etc/DEBUG for instructions.

Thanks.

No need to confess.

Thanks for going through the trouble.
The file is precompiled, so you'd need to rebuild Emacs (or to use
M-C-x to reevaluate the definition) to see the difference.
I've installed my patch, so it should be fixed in the next pretest.
If not, please reopen the bug.
