bug#4838: autocompletion broken

[Angelo Borsotti]

To: emacs-pretest-bug@gnu.org
Subject: 23.1.50; open file autocompletion missing
From: angelo <angelo@angelo-desktop.i-did-not-set--mail-host-address--so-tickle-me>
--text follows this line--

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:

Run Emacs, select File->Open File, and type the first characters
of an existing file. The autocompletion feature does not display
the files whose name starts with the introduced characters.

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/23.1.50/etc/DEBUG for instructions.
