This bug report will be sent to the XEmacs Development Team,
not to your local site managers!!
Please write in English, because the XEmacs maintainers do not have
translators to read other languages for them.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
On my SuSE Linux 7.3, with kernel 2.5.8, XFree v 4.2:
Open KDE Konsole, su to root. Start xemacs.
Following message appears:
-----
Xlib: connection to ":0.0" refused by server
Xlib: Invalid XDM-AUTHORIZATION-1 key (failed key comparison)
Fatal error (11).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
If you have access to the PROBLEMS file that came with your
version of XEmacs, please check to see if your crash is described
there, as there may be a workaround available.
Otherwise, please report this bug by running the send-pr
script included with XEmacs, or selecting `Send Bug Report'
from the help menu.
As a last resort send ordinary email to `crashes(a)xemacs.org'.
*MAKE SURE* to include the information in the command
M-x describe-installation.
If at all possible, *please* try to obtain a C stack backtrace;
it will help us immensely in determining what went wrong.
To do this, locate the core file that was produced as a result
of this crash (it's usually called `core' and is located in the
directory in which you started the editor, or maybe in your home
directory), and type
gdb /usr/X11R6/bin/xemacs core
then type `where' when the debugger prompt comes up.
(If you don't have GDB on your system, you might have DBX,
or XDB, or SDB. A similar procedure should work for all of
these. Ask your system administrator if you need more help.)
Lisp backtrace follows:
Segmentation fault
----
No core is dumped (or at least, I can't find it..)
(I've done 'find / -name "core"' without relevant result..)
If I do "xhost +localhost" (which I often forget.. :-) ), everything
works fine.
This started happening after I changed to kernel 2.5.8.

You can not start X applications under root without setting the
XAUTHORITY environment variable appropriately. This should do the
trick:
XAUTHORITY=$HOME/.Xauthority; export XAUTHORITY
(or
setenv XAUTHORITY $HOME/.Xauthority
if you use csh [shudder] as root's shell)
Then you can run X applications (including XEmacs) as root.

Yeah, he figured it out (at the end he mentions xhost +localhost).
But we need to get XEmacs to output a sensible message, not crash.
I don't think 21.4 crashes, but I'll have to check.

Don't ask how you can "do" free software business;
ask what your business can "do for" free software.

Thanks for the swift response.

My point exactly.. Segfaults often indicate that someone/something has
misbehaved.

21.4 is the version I'm using.
Well, to me this is a non-problem; just thought I'd let you know... Let me
know if there's anything I can do to help.

trick:
XAUTHORITY=$HOME/.Xauthority; export XAUTHORITY
(or
setenv XAUTHORITY $HOME/.Xauthority
if you use csh [shudder] as root's shell)
Both of those are no-ops. If XAUTHORITY is unset, $HOME/.Xauthority is
used instead.
The problem is that "su" is changing $HOME, so $HOME/.Xauthority is no
longer valid.
You need to use the actual path to the appropriate directory, e.g.
XAUTHORITY=/home/asmund/.Xauthority ; export XAUTHORITY
