When trying to run version 2.4.4.5 `gdmflexiserver` or `gdmflexiserver
-xnest` with gnome 2.4.1 I either fail to get a new screen or XFree86
crashes. 

When I run `gdmflexiserver` the monitor flickers like it is taking me
to a new screen but the monitor stays dark.  I have to ctrl+alt+f9
back to my original display.  If I run `gdmflexiserver -xnest` then
XFree86 and gdm actually crash and drop me to a console.  Using
`gdmflexiserver -xnest` also produces the following errors.

/var/log/messages:
Dec 18 21:34:56 compass gdm[57837]: GDM file gdm.c: line 2852
(N/A):Cannot run setegid to 92

(92 is the id for gdm)


Last message in XFree86 log:
Fatal server error:
xf86OpenConsole: VT_SETMODE VT_PROCESS failed


I did not have this problem in gnome 2.4.0 and this machine's current
incarnation never had gnome 2.4.0 installed since I first thought this
was a problem with the FreeBSD port upgrade and something from the old
port conflicting with the new port.


I see that the gdm binaries are not setgid and are owned by root.  I
can run both commands fine if I am logged into gnome as root which
leads me to believe that this is a permission problem.

The following was suggested on the freebsd-gnome@freebsd.org:

Known bug: http://bugzilla.gnome.org/show_bug.cgi?id=127780.  I think
this has to do with the following commit:

* daemon/errorgui.c, daemon/slave.c: be even analer (is that a word?)
about the setuid stuff here (it can't actually fail, but just in case,
we're being paranoid)  Also reset the environment and desetuid for the
setup program even though that's not really needed.

Yes you are correct.  Fixing in HEAD and gnome-2-4 branch.  Doh!. 
It's a good catch though since that setegid would have been useless
otherwise and provided little security of mind (the group should in
fact be GdmGroupId anyway ...)
