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 [email protected] mailing list.

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

This is only a suggestion, but in my opinion it would be very convenient
if the different completion result types in *Completion* buffers would
use different faces.

For example when completing filenames

  - directories would use the dired-directory face,
  - symlinks would use the dired-symlink face, and
  - normal files would stay in the default face.

Using separate faces (maybe inheriting from the dired faces) would be
even better.

I think different faces are much better to distinguish than only the "/"
to distinguish directories from files.  (Currently there's no difference
between symlinks and normal files at all.)

The same could be done for symbol completion, where one might want to
distinguish variables from functions and so on.

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/share/emacs/23.0.90/etc/DEBUG for instructions.
