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:

To reproduce:
    1. emacs -nw -q in screen
    2. M-x server-start
    3. switch to Linux console (Ctrl + Alt + F1)
    4. emacsclient -t

Emacs segfault.
