23.0.60; Crash when running as root

[Christian Faulhammer]

Hi,

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 address@hidden mailing
list.

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

Starting Emacs as root gives me a segmentation fault.  Current HEAD
from 29 May 2008 13:00 CEST.  Text mode works fine, also running as a
normal user.
