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 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
/Applications/Emacs.app/Contents/Resources/etc/DEBUG for instructions.

Unfortunately, I cannot reproduce it. Could you, please, describe the
steps, starting with "emacs -Q"?

Thanks, and best regards, Michael.

No, I don't know how I got here.  If you can't imagine a way that it  
happens, please feel free to close the bug.

I cannot reproduce this here.  Could you apply the patch below (by hand,
probably) and then do C-M-x inside the `completion--some' function to
activate this new definition and then reproduce the problem?  It will
hopefully give us a more complete backtrace.

PS: (minibuffer.el is preloaded, so using C-M-x will save you from
having to byte-compile the file and re-dump Emacs).

I'd love to, but unfortunately I can't reproduce it either, and I  
don't know what I did to get myself in that state.
